Key takeaway
3D Projection Mapping for Kolkata’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 Kolkata that plays out at venues like Biswa Bangla Convention Centre, Science City, Netaji Indoor Stadium, and across Salt Lake, New Town, Park Street, Ballygunge.
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.
What’s included
- 20K–40K lumen laser projectors
- Custom 3D content & storyboards
- Edge blending & warping (Pixera, Disguise)
- Heritage façades, cars, cakes & stages
Equipment we carry
Why Kolkata chooses Prime AV
- Crews and trucks positioned for fast load-in at Netaji Indoor Stadium and venues in Park Street and Ballygunge.
- Towers are built on load-spreading base plates, ballasted, and positions are physically marked so a realignment check before each show takes minutes.
- Audio stem and mixed show track used for synchronisation
- Working knowledge of West Bengal venue rules, power sanctions and permission timelines.

Local conditions
Producing 3D projection mapping in Kolkata
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. The Kalbaisakhi nor'westers in April and May are the design case here: they arrive in minutes with 70–90 km/h gusts, which means outdoor truss in Kolkata is ballasted and signed off for wind loading rather than merely sheeted against rain. Humidity sits near 80% from April to October and the Hooghly keeps overnight dew heavy enough that an outdoor projection surface will fog by 4am and a lectern mic capsule picks up moisture if left uncovered. Jun–Sep monsoon, when the low-lying southern and central wards waterlog within an hour of a heavy cell; and Sep–Oct if you need any inventory at all for something other than Puja.
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. CESC's city network is genuinely one of the better urban utilities in India, so indoor venues run on house power confidently. Puja pandals are a different exercise: temporary sanctioned connections are applied for formally through CESC or WBSEDCL well in advance, and the load per pandal is capped at what the application granted. Maidan and open-ground events are DG-fed with acoustic enclosures under WBPCB norms.
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. Kolkata Municipal Corporation handles structures, the Kolkata Police Commissioner's office with the local police station licenses pandals and loudspeaker use, and WBPCB applies the noise rules with a 10pm to 6am silence period and a time-boxed festival relaxation. The Maidan is Army land, so an event there needs Eastern Command's NOC as a genuine step in the critical path rather than a formality. Drone operation is limited by the Dum Dum airport zone and by Fort William's restrictions over central Kolkata.
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. Larger goods vehicles are barred from central Kolkata through the day, and arrival timing is dictated by which Hooghly crossing the truck uses. The Puja constraint is unlike anything else in India: pandals in the north Kolkata lanes around Shyambazar, Kumartuli and Bagbazar are reached only by handcart for the final 200m, the bamboo structure is complete before any kit arrives, and the hang points are the structure the decorator built, so the rigging design has to be agreed with the pandal fabricator weeks earlier.
Season & booking
From Mahalaya through Lakshmi Puja and on to Kali Puja, roughly late September to early November, every scaffolder, generator, line array and lighting rig in eastern India is committed and rates reflect it. The Kolkata International Film Festival in November and the Boi Mela in late January take the auditoria, and Poila Boishakh in mid-April brings its own cluster of cultural programming. Peak demand runs Oct–Feb.
Crew & dispatch
Own Kolkata base, which is also the practical origin for Patna, Ranchi, Bhubaneswar and Guwahati work. Load-in support covers Park Street, Ballygunge and the rest of the city.
What it costs here
Outside Puja this is a value market with strong, experienced local technical labour at reasonable day rates, so a two-day conference costs appreciably less here than the same build in Mumbai or Delhi. Inside the Puja window the same inventory prices at a multiple and has to be committed months ahead, which is a conversation to have in June rather than in September.
Local expectations
A Bengali audience for live music will notice a coloured PA and say so — Rabindra Sangeet, band and classical programming here want natural tonality and a low noise floor rather than brute level, and the vocal chain is judged more closely than the lighting. Puja committees expect continuous operation across five days, which means shift rotation, a crew rest plan and spares on site rather than in the warehouse. Bengali-language compering is the default and the committee's own hierarchy governs stage access.
Specification
3D Projection Mapping: technical specification
| 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 Kolkata
| Venue | Capacity | Production note |
|---|---|---|
| Biswa Bangla Convention Centre | Around 2,500 in the main hall plus a large grand ballroom at New Town | The city's only purpose-built modern convention venue, with generous clear height and working docks, which makes it the default whenever a design needs hung loads rather than towers. |
| Science City | Around 2,200 in the Main Auditorium with a smaller Mini Auditorium alongside | A fixed-seat theatre with house rigging positions and a fixed projection throw, so screen geometry is decided by the building and additional loads need the venue's engineering sign-off. |
| Netaji Indoor Stadium | Around 12,000 in concert configuration | Roof rigging is effectively unavailable, so the entire package is ground-supported, and the only vehicle approach runs through the congested Maidan roads under police bandobast on event days. |
| Rabindra Sadan | Around 1,000 seated | A cultural-complex auditorium with house infrastructure and a protective attitude to it, so visiting rigs work within the existing hang points and the build window is tight between programmes. |
| ITC Royal Bengal | Around 1,500 banquet across the ballroom and pre-function | Modern hotel with a usable service dock, but New Town traffic and the venue's own guest-movement rules push load-in to overnight slots. |

Risk control
What goes wrong, and how we stop it
What can go wrong
How we prevent it
- What can go wrong
A projector tower settles overnight in soft ground and the whole blend is out by morning.
How we prevent itTowers 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 itIP-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 itThe calculation includes measured surface reflectance, not an assumed figure, and a test projection on the actual material is done at survey wherever access allows.
- What can go wrong
The audience ends up standing off the designed viewing axis and the 3D illusion collapses.
How we prevent itThe viewing position is part of the design and is barricaded or seated on site, with content checked from the extreme left and right of the intended crowd area.
Honest comparison
Is this the right choice for your event?
- LED wall instead of projection mappingOur verdict
LED beats projection on brightness, on reliability and in any lit environment. But it cannot map onto an existing building, a car or a cake, and at 400 square metres of heritage façade it is simply unaffordable. If the surface is the story, map it; if you need a rectangle that works in daylight, use LED.
- Stock content instead of bespoke animationOur 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 unitsOur 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.
