Turn any sketch into a photorealistic render — 60-second AI, geometry preserved
Vizbase is a sketch-to-render AI that turns hand drawings, 3D model views, and floor plan screenshots into photorealistic still images in roughly 60 seconds. Upload your sketch, describe your materials and lighting intent in plain language, and receive a bright, airy, magazine-quality render — with your proportions and lines intact. The geometry-preserving mode keeps your walls vertical, your windows where you drew them, and your spatial logic correct, while applying realistic finishes and natural light on top. Free tier: 5 renders per month. 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 directly. The SketchUp native plugin sends the active viewport with one click; 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.
Geometry-preserving render: your lines, 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
Within seconds 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". Use the geometry-preserving mode (Gen 2.2) to lock your structural lines while the AI applies finishes and light on top.
Photorealistic render in 30–60 seconds
Your sketch becomes a bright, airy, magazine-quality photorealistic image with your proportions intact. Download it for client presentations, iterate on individual elements with inpainting (change just the floor or the glazing without re-rendering the whole scene), or upscale to 6× resolution 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.
60-second turnaround 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 fastest path from sketch to photorealistic still.
Questions about sketch-to-render AI
Does Vizbase keep my proportions and geometry when rendering from a sketch?
Yes — this is what the geometry-preserving mode (Gen 2.2) is designed for. It encodes the spatial structure of your input image using LAB colour space and blends it with the generated output, so walls stay vertical, windows stay where you drew them, and room proportions are maintained. Materials and lighting are added on top without distorting your design intent.
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. The AI automatically detects whether the scene is an interior or exterior and applies appropriate lighting and material logic.
How fast is the sketch-to-render turnaround?
Typically 30–60 seconds per render. Upload your sketch, describe your materials and lighting intent in plain language, and the photorealistic image is ready before a client email finishes loading. You can iterate — swap a material, change the lighting mood, or edit a single element — and each iteration takes another 30–60 seconds.
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 render takes about 60 seconds. You can present all three options to a client in under five minutes from a single sketch input.
