Specifications

Features

Calculates light, shadows, materials, transparency, diffusion, reflection, ClearFinish™, and refraction from a surface’s properties. AccuRender’s accurate lighting modeling produces sophisticated effects and high-quality images.

Easy to use, works seamlessly inside AutoCAD, and provides a host of features that speed and simplify image rendering.

Uses both raytracing and radiosity to create sophisticated single-frame images, panoramas, and animations.

Assigns materials to an layer, color, or object.

Automatically calculates indirect light, hard and soft shadows, color bleeding, reflections, translucency, transparency, refraction, depth of field, and depth attenuation.

Produces panorama files. When viewing a panorama file, you can move around within the rendered image.

Supports multiprocessors and background processing.

Includes realistic mathematically generated 3-D plants with seasonal variation, giving realistic plants, shadows, and reflections.

Includes thousands of materials, hundreds of plants and light fixtures.

Works inside AutoCAD. Render changes to the model immediately. You never need to export or start over.
