Which Siliguri venues do you work at?

Cinnamon Siliguri (Up to 900 seated across banquet halls); Kanchenjunga Stadium (20,000-plus with the field in use); Mayfair Siliguri (Up to 800 across ballroom and lawns). Sevoke Road property with a workable approach but no real dock — unloading happens on the service side of a busy arterial, and the hall's beam-to-slab gap keeps the lighting trim low. We also cover hotels, farmhouses and open grounds across Sevoke Road, Hill Cart Road, Matigara, Pradhan Nagar, Champasari.

How is projection mapping different from a normal projection screen?

A screen is a flat rectangle and the content is a video. Mapping treats an irregular 3D object as the display surface, so the content is rendered against a measured model of that object and warped, blended and masked per projector. The work is in the survey, the geometry and the alignment far more than in the projectors themselves.

How many lumens does my building need?

It depends on surface area, material reflectance and ambient light, not on size alone. As a planning figure we budget roughly 250 to 400 lumens per square metre of lit surface for a reasonably dark site on light stone, which puts a 400 square metre façade at 100,000 lumens or more. Dark granite and nearby street lighting both push that figure up sharply.

How long does the content take to produce?

Five to seven weeks for a three to five minute façade show, from storyboard through animatic to final render with sound design. The clock cannot start until the projector study is signed off, because the animation is authored onto the specific geometry and camera positions, so an early survey is what protects the schedule.

Can you map onto a heritage monument?

Technically yes, and we do. Practically it requires permission from the site authority, a no-touch approach where nothing is fixed to the structure, projectors positioned on ballasted free-standing towers, and usually restrictions on show hours and sound level. That permission file is the long lead item, not the content.

Key takeaway

3D Projection Mapping in Siliguri is quoted against your guest count, venue and run of show. Trading-family weddings pay well for visible spend — stage, floral, LED and entry — and negotiate hard on crew days and infrastructure. Tea-industry and corporate roadshow work is modest in value but reliably repeating across a season. The cost of getting gear here at all has to sit honestly in the quote, because freight and the hill transfer are not absorbable. Durga Puja and Kali Puja in Sep–Oct are absolute — every sound box, dimmer, truss span and technician in the district is committed to pandals for a fortnight, and anything else booked in that window will not be serviced. The Christmas–New Year hill-tourist peak locks accommodation and vehicles. Add the Teesta Tea and Tourism Festival, Saraswati Puja in Jan–Feb, and the Bengali wedding dates clustered in Agrahayan and Magh — so we quote within 24 hours and hold dates first-come.

3D Projection Mapping for Siliguri’s biggest events

Projection mapping starts with a survey, not a storyboard. We photogrammetry-scan or LiDAR-measure the surface — a façade, a stage set, a car, a cake — and build a 3D model that matches the real object within a few centimetres. The projectors are then positioned virtually against that model to check throw ratio, keystone, shadowing from balconies or trees, and whether any part of the surface falls outside the beam. Only once the projector positions are fixed does content production begin, because a mapped animation is authored against a specific camera position and cannot simply be moved later.

The surface is the instrument here — its material, reflectance, depth and the audience's viewing axis decide projector count, angles and whether the illusion reads at all. In Siliguri that plays out at venues like Cinnamon Siliguri, Kanchenjunga Stadium, Mayfair Siliguri, and across Sevoke Road, Hill Cart Road, Matigara, Pradhan Nagar.

Brightness is the engineering constraint that decides the budget. Perceived image brightness depends on lumens, surface area, the reflectance of the material and the ambient light falling on it. Stone and painted plaster reflect perhaps 20 to 35 per cent of what hits them; dark stone far less. A heritage façade of 400 square metres with street lighting nearby can need 100,000 lumens or more in total, which is three or four stacked 30K-class laser projectors per angle. Laser phosphor sources are the standard now because they hold brightness and colour across a run, start instantly and tolerate the dust and heat of an outdoor build far better than lamps.

Local conditions

Producing 3D projection mapping in Siliguri

Weather & the rig

Mapping is defeated by air as much as by rain — haze, dust and humidity scatter the beam and soften a blend, so brightness headroom is specified against local conditions. Three distinct hazards. Jun–Sep brings Himalayan foothill rain of 2,500 mm-plus with the Mahananda and Teesta running high and Sevoke Road waterlogging. Nov–Jan brings dense Dooars fog that closes Bagdogra for hours and destroys any projection or aerial plan. Worst for a build is Apr–May, when Kalbaishakhi squall lines arrive off the plains with twenty minutes' warning and 60–70 km/h gusts — the single biggest cause of collapsed outdoor structures in north Bengal. Jun–Sep monsoon with its landslide closures on the hill routes; and Apr–May squall season for any outdoor build without a wind plan.

Power & redundancy

Stacked 30K-class projectors each draw several kilowatts continuously for the whole run, so projection needs a dedicated, stable, uninterrupted supply rather than a share of the event distribution. WBSEDCL supply has frequent short interruptions and noticeable voltage swing through the wholesale and Sevoke Road belt, so DG with automatic voltage regulation is standard and a stabiliser ahead of LED processors is sensible. Tea-garden and Dooars-edge venues are entirely generator-fed, with fuel carried in because the estate roads make a mid-show bowser run unrealistic.

Permits & noise rules

Mapping a building means permission to light it, towers on public or heritage ground, and usually a negotiated blackout of nearby street lighting for the show window. Siliguri Municipal Corporation for the licence and temporary-structure permission, the Siliguri Police Commissionerate for the public-performance and loudspeaker licence, and West Bengal Pollution Control Board noise rules with the 10 pm outdoor limit — Bengal's enforcement spikes around Kali Puja and Diwali, when the sound-box crackdown is active and genuine. Bagdogra is a civil enclave on an Air Force base 13 km out, which effectively closes drone operations. International-border proximity means the district administration expects intimation for any large gathering.

Load-in & access

Projector towers, ballast and enclosures have to be placed on a precise viewing axis that is often a road or a public plaza, so access and closures drive the build plan. Siliguri is unusually easy to supply for its size because NJP railhead and Bagdogra air cargo both work — Kolkata is 560 km and 11–12 hours, so heavy LED and truss generally rail or fly rather than drive. Onward hill work is the hard part: NH-10 along the Teesta towards Kalimpong and Gangtok has landslide closures and a practical vehicle-length limit, and the Darjeeling road needs small trucks and tempo travellers only. Plan a transfer at Siliguri rather than a through-run.

Season & booking

Durga Puja and Kali Puja in Sep–Oct are absolute — every sound box, dimmer, truss span and technician in the district is committed to pandals for a fortnight, and anything else booked in that window will not be serviced. The Christmas–New Year hill-tourist peak locks accommodation and vehicles. Add the Teesta Tea and Tourism Festival, Saraswati Puja in Jan–Feb, and the Bengali wedding dates clustered in Agrahayan and Magh. Peak demand runs Oct–Mar.

Crew & dispatch

Local crew with working stock in Siliguri; large-format LED and specialist inventory railed to NJP or flown into Bagdogra from Kolkata rather than driven, with at least 48 hours in hand for the handover. Load-in support covers Pradhan Nagar, Champasari and the rest of the city.

What it costs here

Trading-family weddings pay well for visible spend — stage, floral, LED and entry — and negotiate hard on crew days and infrastructure. Tea-industry and corporate roadshow work is modest in value but reliably repeating across a season. The cost of getting gear here at all has to sit honestly in the quote, because freight and the hill transfer are not absorbable.

Local expectations

A genuinely mixed market — Marwari weddings run a long multi-day sequence with sangeet at full volume, Bengali weddings keep the shehnai, conch and uludhwani in acoustic space, and both expect the curfew honoured because Bengal police act on it. Pandal work answers to a puja committee, so the plan is presented to a room. Bengali and Hindi announcements with Nepali recognised in the hill-adjacent crowd.

Specification

3D Projection Mapping: technical specification

Typical 3D projection mapping specification supplied in Siliguri.
Specification	Detail
Projector class	20,000 – 40,000 ANSI lumens, laser phosphor or RGB laser, 3-chip DLP
Surface reflectance assumption	20 – 35 per cent for stone and painted plaster, lower for dark granite
Typical façade budget	Approximately 250 – 400 lumens per square metre of lit surface, ambient dependent
Blend overlap	10 – 20 per cent soft-edge between adjacent projectors
Media servers	disguise gx/vx, AV Stumpfl Pixera, Dataton Watchout
Survey method	Photogrammetry or LiDAR scan to a 3D model accurate within a few centimetres
Alignment window	Night-time only, four to eight hours for a multi-projector façade
Content pipeline	Cinema 4D or Blender to UV-mapped render, delivered as image sequence
Show length	3 – 12 minutes, usually looped with timecoded audio
Weather protection	IP-rated projector enclosures with filtered forced-air cooling for outdoor runs

On site, the work is warping, blending and masking. Each projector's output is warped onto the surface geometry using a media server — disguise, Pixera or Watchout — with overlap regions of 10 to 20 per cent soft-edge blended so no seam is visible. Masks cut the beam off windows, balconies and anything that must stay dark. Alignment is done at night with the actual content and takes hours, not minutes, and it must be re-checked if a projector is bumped or a tower settles. We lock projector positions with ballasted towers and mark every position so a knocked unit can be returned to alignment rather than re-mapped.

Venues

Where we work in Siliguri

Venue	Capacity	Production note
Cinnamon Siliguri	Up to 900 seated across banquet halls	Sevoke Road property with a workable approach but no real dock — unloading happens on the service side of a busy arterial, and the hall's beam-to-slab gap keeps the lighting trim low.
Kanchenjunga Stadium	20,000-plus with the field in use	The city's main large-crowd venue, right in the centre: no permanent rigging, turf and track protection needed before any vehicle crosses, a single usable service gate, and a surrounding commercial block where the approach jams solid by 9 am.
Mayfair Siliguri	Up to 800 across ballroom and lawns	Resort-format property on the Matigara side with lawn space and parking; the open lawn is exposed to the pre-monsoon squall line, so anything tall here needs guying and a wind-abort trigger written into the plan.
Sinclairs Siliguri	Up to 500 seated across halls	Established Pradhan Nagar hotel sized for conferences and mid-scale receptions; load-in is lift-based from a tight forecourt and parking is the practical limit on how many vehicles can be on site at once.
Tea-garden and Dooars-edge venues	300–1,500 depending on the estate	The estate bungalow-and-lawn settings that destination clients ask for sit outside the municipal supply area entirely, so they are DG-only, the estate roads will not take a heavy truck after rain, and the Forest Department takes an interest wherever the plot abuts an elephant corridor.

Risk control

What goes wrong, and how we stop it

What can go wrong

How we prevent it

What can go wrong
Content is authored before projector positions are fixed, so the animation does not sit on the geometry.
How we prevent it
Content production does not begin until the projector study is signed off, because the mapping is authored against those exact camera positions.
What can go wrong
A projector tower settles overnight in soft ground and the whole blend is out by morning.
How we prevent it
Towers are built on load-spreading base plates, ballasted, and positions are physically marked so a realignment check before each show takes minutes.
What can go wrong
Dust and heat in an outdoor enclosure cause thermal shutdown mid-show.
How we prevent it
IP-rated enclosures with filtered forced-air cooling, filters changed daily on a multi-night run, and internal temperature logged during rehearsal.
What can go wrong
Brightness is calculated from lumens alone and the dark stone façade swallows the image.
How we prevent it
The calculation includes measured surface reflectance, not an assumed figure, and a test projection on the actual material is done at survey wherever access allows.

Honest comparison

Is this the right choice for your event?

Stock content instead of bespoke animation
Our verdict
Stock loops and generative visuals genuinely work for ambient architectural washes and for leaner budgets. They cannot do a reveal, a narrative or anything that respects the building's actual architecture, because they are not authored to your geometry.
Fewer, brighter projectors instead of more units
Our verdict
Fewer angles means fewer blends and a faster alignment, which is the right trade on a flat surface. Any building with depth, recesses or wings needs multiple angles regardless of total lumens, or the recesses stay dark.
Architectural lighting instead of mapping
Our verdict
For a façade that only needs to look beautiful, uplighting and colour washes cost a fraction, go up in a day and work in light rain. Mapping is for when the building has to perform rather than just glow.
