Notes
(0098017) git (administrator) 2021-01-09 23:24	Branch CR31646_3 has been created by kgv. SHA-1: ab34662b0346ac946e345f39781150ae31dee410 Detailed log of new commits: Author: kgv Date: Mon Jan 4 12:17:44 2021 +0300 0032039: Visualization, TKOpenGl - implement simple shadow mapping for a direct light source Graphic3d_CLight::ToCastShadows() - added new property defining if light should cast shadows (ignored by Ray-Tracing). OpenGl_ShaderManager::stdComputeLighting() now implements shadow mapping for directional lights. OpenGl_ShaderManager::prepareGeomMainSrc() now handles copying of arrays. OpenGl_Context::ShadowMapTexUnit() - added property defining an offset for shadow map texture units. OpenGl_ShadowMap - added new class storing shadow map FBO with parameters. OpenGl_View::prepareFrameBuffers() - added resizing of shadow map FBOs. OpenGl_View::Redraw() - added section redrawing scene into shadow map FBOs via OpenGl_View::renderShadowMap() method. vrenderparams - added new parameters -shadowMapResolution and -shadowMapBias. Author: kgv Date: Thu Jan 7 23:10:27 2021 +0300 0032041: Modeling Data - Access violation ExchangeUV in Geom_BezierSurface Added missing NULL-checks to Geom_BezierSurface::ExchangeUV() and Geom_BSplineSurface::ExchangeUV(). 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. Author: kgv Date: Mon Jan 4 12:13:38 2021 +0300 0032040: Visualization, OpenGl_View - merge OpenGl_View_Redraw.cxx into OpenGl_View.cxx Author: kgv Date: Mon Jan 4 03:26:51 2021 +0300 0032038: Visualization, OpenGl_View - move out framebuffer initialization from ::Redraw() to ::prepareFrameBuffers() Author: kgv Date: Mon Jan 4 11:53:24 2021 +0300 0032037: Visualization - move V3d_View::FitMinMax() to Graphic3d_Camera::FitMinMax()
