2023년 10월 24일부터 현재 버전 3.2.0까지 OSPRay의 3개 버전을 모았습니다. 모든 버전은 제공사의 공식 설치 파일로 연결됩니다.
| 버전 | 날짜 | 크기 | 파일 |
|---|---|---|---|
| 3.2.0최신 | 2024년 7월 23일 | — | 64비트 MSI 릴리스 노트- Sampling improvements:
- Better performance (lower rendering time and faster convergence)
- More pleasing blue noise enabled when the total number of frames to be accumulated is known in advance and set as the targetFrames parameter at the framebuffer
- Note a maximum of 64k samples is supported
- Improved denoiser image operation:
- User-controlled quality levels via parameter quality
- Optionally denoise alpha channel as well, enabled via parameter denoiseAlpha
- Support half-precision (16 bit float) texture formats OSP_TEXTURE_[RGBA16F|RGB16F|RA16F|R16F] and two-channel 32 bit float textures OSP_TEXTURE_RA32F
- New parameter limitIndirectLightSamples for the pathtracer which limits the number of light samples after the first non-specular (i.e., diffuse and glossy) bounce to at most one
- Implement MIP Mapping for better texture filtering. If the additional memory per texture needed cannot be spared, applications can disable the generation of MIP maps with device parameter disableMipMapGeneration
- The backplate (background texture) is now always sampled at the pixel center and thus not blurred by the pixel filter anymore
- Avoid color bleeding across eye-subimages when stereo rendering
- Superbuild uses binary packages of Open VKL
- Removed Intel ISPCRT dependency (ISPC compiler is still needed):
- oneAPI Level Zero Loader is no longer necessary
- zeContext and zeDevicedevice parameters are no longer supported
- ispcrtContext and ispcrtDevicedevice parameters are no longer supported
- Clarify the size of OSP_BOOL to be 1 byte
- Fix artifacts occasionally appearing with gpu device
- The new minimum versions of dependencies:
- Embree v4.3.3 (better error reporting)
- Open Image Denoise v2.3 (better image quality with HIGH quality mode, added FAST quality mode)
- rkcommon v1.14.0

| 3.1.0 | 2024년 2월 22일 | — | 64비트 MSI 릴리스 노트- Principled and Luminous materials support emissive textures
- Add native support for disc and oriented disc geometry
- Add support for mirror repeat and clamp to edge texture wrap modes
- GPU device now also supports motion blur
- Improve noise in reflections of ThinGlass
- Improve adaptive accumulation: working with GPU, fix correlations
- Fix indirectly seen albedo and normal buffer
- Fix artifacts when using specular texture for Principled
- Fixes for PixelFilter
- Parameter was ignored (always using the default Gaussian)
- Avoid a shift/misalignment within the pixel for first sample
- Fix empty image on Windows when focusDistance=0
- Fix missing SDK headers for ISPCDevice*
- The new minimum versions of dependencies:
- Embree v4.3.1
- Open VKL v2.0.1
- Open Image Denoise v2.2 (better quality with fine details, support AArch64 CPU on Linux)
- ISPCRT v1.23.0 (uses environment variable ISPCRT_GPU_DRIVER to select GPU to run on when multiple (i)GPUs are present)
- rkcommon v1.13.0 (fixes crash using GPU and emissive geometry) |
