Summary 0030476: Visualization, Path Tracing - Adaptive Screen Sampling leads to unstable results
Revision 2019-02-08 20:08 by kgv
Description Activation of Graphic3d_RenderingParams::AdaptiveScreenSampling option leads to unstable results of Path Tracing algorithm. As result, Jenkins tests show regular screenshots deviations.

Note that for some reason, specifying 1024x1024 rendering resolution does not have this side effect.

In addition, the algorithm relies on GL_NV_shader_atomic_float extension,
which is currently implemented only on NVIDIA hardware, limiting AdaptiveScreenSampling usability.
