Fujiyama is free and open source, distribution oriented ray-tracing renderer designed to handle production image rendering.

Platforms

1. Linux
2. Mac OS X
3. Windows

Rendering

1. Multi-threaded rendering - dynamic assignment of tile rendering per thread
2. Rendering preview - fbview shows rendering progress
3. Region rendering - accelerates distribution rendering pipeline
4. Tile based rendering

Supported Primitives

1. Triangle Mesh - Compact representation
2. Bezier Curves - Unlimited smoothness subdividing in render time
3. Volume Primitive - Ray traced self-shadowing
4. Point Cloud - Can be rendered as particles

Procedure Plugin

1. Volume Filling Procedure - Pyroclastic clouds procedure provided
2. Volume Filling Procedure - Spline wisps procedure provided
3. Volume Filling Procedure - Surface wisps procedure provided

File format

1. Original mipmap format - hdr2mip is provided
2. Original framebuffer format - fb2exr is provided
3. Command-like scene description language - works with text filter tools
4. Python Binding scene description - can utilize control structures and libraries
5. FrameBuffer Viewer - displays *.fb and *.mip
6. Input format - *.mesh, *.ply, *.obj, *.mip, *.hdr, *.jpg (through Python API)
7. Output format - *.fb, *.exr (through Python API)

Lighting

1. Point light - traditional point light
2. Grid light - typical area light with single/double-sided option
3. Sphere light - another area light
4. Dome light - supports IBL with environment map

Animation

1. Camera motion blur - sampling non-linear camera motion
2. Transform motion blur - sampling non-linear object motion
3. Velocity attribute motion blur - useful for point count changing geometry

Shading and Texture

1. On demand reading of mipmap - unlimited number of texture images
2. Pluggable shader DSO - shaders can be written in C/C++
3. Subsurface scattering - implemented in shader
4. Bump mapping - perturb normals based on mipmap images
5. Primitive groups - multiple shader assignment on triangle mesh

Acceleration structure

1. Grid accelerator - for meshes (dense distribution)
2. BVH accelerator - for object instances (sparse distribution)
3. Object instance - saves memory usage

Sampling and Filtering

1. Gaussian and Box pixel filters - supports filter width bigger than 1 pixel
2. Adaptive grid pixel sampling - subdivides pixels based on color threshold
3. Uniform grid pixel sampling
4. Jittered pixel sampling

Extensibility

1. Rendering callbacks - 5 points to hook rendering process

Under development

• Deformation motion blur
• AOV support
