RadeonProRender ANARI device

Description

This is implementation of ANARI device based on RadeonProRender engine

Implementation details

Camera

  • supported types: perspective and orthographic
  • transform parameter overrides position, direction and up parameters
  • imageRegion parameter is not supported now
  • focusDistance and apertureRadius parameters are only supported by perspective camera
  • both cameras have an additional parameter sensorHeight. Sensor width will be calculated using aspect parameter. Default sensor height is 24 mm
  • orthographic camera has an additional parameter orthoHeight. It determines the area which the Orthographic camera projection will cover. Width will be calculated using aspect parameter. Default value is 1

Geometry

  • curve geometry type is not supported now
  • general parameters (primitive.color, primitive.attribute, primitive.id) are not supported
  • vertex.color can only accept float32 types (FLOAT32, FLOAT32_VEC2, FLOAT32_VEC3, FLOAT32_VEC4)
  • vertex.normal can only accept FLOAT32 values
  • primitive.index can only accept uint32 values and vectors

Volumes

  • data in spatial fields can be only in float32 format (ARRAY3D of FLOAT32)
  • color can only accept float32 types (FLOAT32, FLOAT32_VEC2, FLOAT32_VEC3, FLOAT32_VEC4)
  • color.position and opacity.position parameters are not supported

Features which are not implemented yet

  • object introspection
  • stereo mode of cameras
  • depth framebuffer
  • curve geometry
  • KHR_AUXILIARY_BUFFERS
  • ANARI_KHR_TRANSFORMATION_MOTION_BLUR

Dependencies

ANARI SDK must be installed on computer before RPR device building.

Building the device

The repository uses CMake 3.11+ to build the device For example, to build (must be in a separate directory from the source directory), you can do:

UNIX-like systems

cd path/to/source
mkdir build
cd build
cmake ..
cmake --build . -t install

It's important to have directory with installed device in LD_LIBRARY_PATH

Windows

Visual studio 17 or 19 must be installed. Building using MinGW may produce an error!

  • create build directory into directory with source code
  • run cmake .. from build directory
  • run cmake --build . from build directory

Also, you can build project from Visual Studio IDE using CMake extension.
