Rendering with PYTHA Raytracing and Radiosity

3D CAD System forPlanning, Presentation and Production

ONE STEP AHEAD OF REALITY

Lighting engineering• The radiosity model uses physically

correct lighting properties• Direct, indirect, adaptive light• Direct and indirect shadow calculation• Shadows for light sources, objects, groups

and layers can be excluded• Associated with switches• Real time mirrors• Transparency

Types of light sources• Point-, spot-, surface-, object lights• Arbitrarily shaped objects• Volume light• Daylight models (season, time, position,

cloud intensity)• LED lights based on textures• HDR light

Light properties• Color (interactive, real time)• Light intensity (Lumen)• Radiation direction• Dimming effect (interactive, real time)• Eulumdat files• Color filter options (interactive, real time)• Different lighting conditions in one scene• Light reflections

Light pen/smoothing pen• Draw light or shadows on any object• Interactive smoothing

Lighting planning• False-color presentation• Measurement of luminance and

brightness (Lux; Candela/sq.m)• Calculation on work plane• Isolux lines

Tools in real time• For groups, objects, faces, light sources,

cameras• Zoom, stretch• Move, copy, rotate• Append, replace, delete parts

Selection• Attributes, part names, groups, layers• About all part attributes• Room culling

…

Textures• Changes in real time• Drag’n drop• Repeat (relative, per meter), interactive

texture coordinates• Zoom, stretch, move, rotate• Mirror textures• Transparency textures (color, alpha channel)• Video textures• Light maps with light-, shadow information

(export Jpeg, Tiff)• Billboards

Material• Physically correct properties• Color, diffuse reflection, shininess• Specular, transparency

Information• Dimensions• Description of objects• Brightness• Density of light on surface• Texture information

Fore- and background• Color, color gradient, texture• 3D background• Animated sky• Foreground with controllers for

animations, cameras

Camera• Arbitrary walk through (with sound) • Collision detection (with sound)• Automatic approach to objects• Arbitrary number of camera positions• Camera movement along splines• Arbitrary aperture• Rotation about eye point or center • Trackball control• Space Mouse support

Presentation mode• Full screen presentation• Jump to selected camera positions• Start animation

Multimedia• Based on parts• Start by clicking or at given distance • Sound-, video files• Dolby Surround Sound• Links to websites…

Real time shader• Phong, Fresnel• Water shader• Bump-, Gloss Maps• Glass shader

Real time rendering• Gouraud shading• Radiosity• Wire frame, shaded lines• Outlines• Hand made drawings (pencil sketch,

comicstyle, watercolors,… - expandable)• Antialiasing• Stereo rendering• Fog• Clipping• Rendering styles can be arbitrarily combined

Animation• Interpolation through various camera

positions• Preview mode with graphic presentation• Animated daylight simulation• Connect actions with camera path

Actions• Move parts• Light switch• Vanish/appear parts• Scale parts• Texture ticker• Slide show• Surface changer• Light show• Video• Projector• Combine actions

Output• Images in any resolution• Optional depth of field, stereo pictures,

alpha mask, Z-Buffer• Views to scale• Hand made drawings (stylish rendering)• Panorama pictures/scenes (automatically)• Individual images of an animation series• Animation as film• VRML-2, OBJ, 3DS• Reports for lighting planning in HTML

(Lux-table, Isolux diagram, material-,texture lists)

• Self starting .exe files…
