Turn any sketch into a photorealistic render — layout kept, no GPU needed
Vizbase is a sketch-to-render AI that turns hand drawings, 3D model views, and floor plan screenshots into photorealistic still images. Upload your sketch, describe your materials and lighting intent in plain language, and receive a bright, airy, magazine-quality render that keeps your layout. Gen 2.0 keeps your finishes and adds natural daylight at the lowest price; Gen 4.0, the newest mode, adds photographic light and materials while staying true to the design. Free tier: 5 credits a month, up to 10 renders. Paid plans from €29/month.
What can I render from?
Pencil, marker, or watercolour sketch
Photograph your hand-drawn sketch on paper (phone camera works fine) and upload it. Vizbase interprets your line work, infers wall planes, window positions, and spatial volumes, then applies photorealistic materials and lighting. Your drawing stays the geometric foundation — the AI adds the finish.
SketchUp, Revit, Rhino, or Blender viewport
Export any 3D viewport screenshot — a SketchUp perspective, a Revit camera view, a Rhino shaded render. Vizbase reads the geometry from the image itself. The SketchUp native plugin captures the active viewport as an image for you; all other tools use a simple screenshot upload. Model detail level does not matter.
Floor plan or section view
Upload a 2D floor plan or section drawing and describe the space. Vizbase can render a photorealistic interpretation of the spatial layout — useful for communicating a plan to non-technical clients or generating quick mood images before a 3D model exists.
Massing model or grey-box render
A plain grey-box SketchUp massing or a simple Revit schematic is enough to produce a compelling render. Vizbase adds cladding, glazing, landscape, and light atmosphere on top of the bare geometry. Use this to present design options at RIBA Stage 2 or equivalent without committing to detailed modelling.
From sketch to render: your layout, AI materials and light
Upload your sketch or model view
Drag in a photo of a hand sketch, a SketchUp screenshot, or a Revit export. Any resolution JPEG or PNG. The AI accepts images from A4 napkin sketches photographed on a phone through to high-resolution model views.
AI analyses your geometry and detects elements
The AI reads your spatial structure — detecting room type or exterior context, identifying walls, floors, ceilings, windows, and major elements — and generates a segmentation mask for each one. No manual tracing or selection needed.
Describe materials and lighting in plain language
Select an element and type a description: "polished Carrara marble", "wide-plank oak hardwood with a matt finish", "deep charcoal painted joinery". Pick Gen 2.0 for quick drafts at the lowest price, or Gen 4.0 for photographic light and materials that stay true to the design.
Photorealistic render, ready to present
Your sketch becomes a bright, airy, magazine-quality photorealistic image that keeps your layout. Download it for client presentations, change a single element such as the floor or the glazing with Refine without starting over, or export it in 4K, 6K or 8K for print.
Describe finishes in plain English — no preset library
There are no dropdown menus or preset material packs. You type what you want and the AI interprets it. Specific descriptions produce specific results. These are examples of prompts that produce photorealistic outputs:
Interiors and exteriors from the same sketch-to-render pipeline
Living rooms, kitchens, offices, lobbies
Upload a sketch or model view of any interior space. Specify finishes per element — floor, walls, ceiling, cabinetry, upholstery, glazing. The AI adds diffused natural light, ambient reflections, and immaculate material finishes for a magazine-spread result.
Facades, massing, streetscapes, landscaping
Upload an elevation sketch or massing model view. Describe cladding material, glazing type, and landscape treatment. The AI renders the facade with bright, even daylight and crisp material detail — suitable for planning submissions and client approval boards.
Time per stage: Vizbase vs traditional rendering
Note: traditional physics-based renderers (V-Ray, Lumion, Enscape) remain superior for animations, real-time walkthroughs, and physically accurate shadow/daylight studies. Vizbase is the quicker path from sketch to photorealistic still.
Questions about sketch-to-render AI
Does Vizbase keep my proportions and geometry when rendering from a sketch?
It keeps your layout and the main pieces of the design: every render starts from your image, and materials and lighting are added on top. Gen 2.0 keeps your finishes and adds natural daylight at the lowest price; Gen 4.0, the newest mode, adds photographic light and materials while staying true to the design. It does not guarantee unchanged geometry, though: small fixtures and repeated joints can drift, so check fine detail before you present.
Can it work from a rough pencil sketch?
Yes. Vizbase processes any 2D image, including photos of hand-drawn pencil or marker sketches. The AI infers the architectural context from line work and shading. A cleaner sketch produces more predictable results, but even a quick napkin sketch will generate a photorealistic interpretation of the space.
What types of input images work best?
Three input types work particularly well: hand-drawn sketches (pencil, marker, watercolour wash), screenshots from 3D modelling software (SketchUp, Revit, Rhino, Blender), and floor-plan or section views exported from CAD tools. All three paths use the same AI pipeline. The more legible the spatial information in the image, the more accurate the result.
Does it work for exteriors as well as interiors?
Yes. Vizbase renders both building exteriors (facades, streetscapes, landscaped plots) and interior spaces (living rooms, kitchens, lobbies, open-plan offices) from sketch inputs. Set the scene type to Interior or Exterior at upload, and Vizbase applies lighting and material logic for that type.
How fast is the sketch-to-render turnaround?
It depends on the render mode. In our tests Gen 2.0 took 26–48 seconds, Gen 4.0 58–66 seconds and Gen 3.0 77–151 seconds per image. Upload your sketch, describe your materials and lighting intent in plain language, and render. You can iterate — swap a material, change the lighting mood, or refine a single element without starting over — and each iteration is a new render of the whole image.
Can I show multiple design options from the same sketch?
Yes. Upload one sketch and describe three different finish schemes — a light Scandinavian scheme, a dark industrial one, and a warm mid-century palette. Each scheme is its own render, so you can present all three options side by side from a single sketch input.
