Robert Swain 618c9e94f0 Scale normal bias by texel size (#26) ... * 3d_scene_pipelined: Use a shallower directional light angle to provoke acne * cornell_box_pipelined: Remove bias tweaks * bevy_pbr2: Simplify shadow biases by moving them to linear depth * bevy_pbr2: Do not use DepthBiasState * bevy_pbr2: Do not use bilinear filtering for sampling depth textures * pbr.wgsl: Remove unnecessary comment * bevy_pbr2: Do manual shadow map depth comparisons for more flexibility * examples: Add shadow_biases_pipelined example This is useful for stress testing biases. * bevy_pbr2: Scale the point light normal bias by the shadow map texel size This allows the normal bias to be small close to the light source where the shadow map texel to screen texel ratio is high, but is appropriately large further away from the light source where the shadow map texel can easily cover multiple screen texels. * shadow_biases_pipelined: Add support for toggling directional / point light * shadow_biases_pipelined: Cleanup * bevy_pbr2: Scale the directional light normal bias by the shadow map texel size * shadow_biases_pipelined: Fit the orthographic projection around the scene * bevy_pbr2: Directional lights should have no shadows outside their projection Before this change, sampling a fragment position from outside the ndc volume would result in the return sample being clamped to the edge in x,y or possibly always casting a shadow for fragment positions past the orthographic projection's far plane. * bevy_pbr2: Fix the default directional light normal bias * Revert "bevy_pbr2: Do manual shadow map depth comparisons for more flexibility" This reverts commit 7df1bab38a42d8a33bc50ca583d4be37bd9c9f0d. * shadow_biases_pipelined: Adjust directional light normal bias in 0.1 increments * pbr.wgsl: Add a couple of clarifying comments * Revert "bevy_pbr2: Do not use bilinear filtering for sampling depth textures" This reverts commit f53baab0232ce218866a45cad6902b470f4cf2c4. * shadow_biases_pipelined: Print usage to terminal		2021-07-24 16:43:37 -07:00
