| Summary | 0032042: Visualization, TKOpenGl - pre-multiply headlight flag into light source position | ||||||||||||
| Description | Currently headlight flag is passed to GLSL program so that transformation has to be applied dynamically. This looks like unnecessary overcomplication - as camera position remains static within frame, it makes sense premultiplying transformation and passing final headlight position. | ||||||||||||

Branch CR32042 has been created by kgv. SHA-1: c262aafaff5398237d85c2ab434141501460ab70 Detailed log of new commits: Author: kgv Date: Fri Jan 8 00:48:29 2021 +0300 0032042: Visualization, TKOpenGl - pre-multiply headlight flag into light source position OpenGl_ShaderManager::pushLightSourceState() now pre-multiplies headlight transformation. Built-in shading GLSL programs have been updated to remove special handling if headlight flag; also removed redundant pre-normalization of light source direction (already normalized implicitly by Graphic3d_CLight interface). Graphic3d_CLight::SetHeadlight() now raises exception in case of ambient light type. OpenGl_ShaderManager::SetLastView() - removed unused property. |
