Scarica OSPRay 3.2.0 per Windows

- 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
