kgv	8e0a2b19ab	0029074: Visualization, TKOpenGl - support Geometry Shader definition ... Graphic3d_TypeOfShaderObject enumeration has been extended by Geometry shader object type. OpenGl_ShaderProgram::Initialize() processes new shader object types when supported by OpenGL version. Declarations.glsl has been fixed so that occFragColor is defined only for Fragment Shader object only (by handling new FRAGMENT_SHADER macros). Improved documentation of Graphic3d_ArrayOfPrimitives class. vshader Draw Harness command has been extended to support definition of Shader Object types other than Vertex and Fragment shader.	2017-09-22 11:51:36 +03:00
kgv	a6dee93dfa	0028811: Visualization - merge texturing support into AIS_Shape class and get rid of AIS_TexturedShape ... AIS_Shape and AIS_ColoredShape now computes Shaded presentation with UV coordinates if texture mapping is enabled in Drawer. OpenGl_Context::SetTextureMatrix() - fixed inconsistent handling of texture cooridnates translation vector. vtexture command has been extended to handle new arguments: * -trsfTrans, -trsfScale, -trsfAngle defining transformation matrix * -setFilter, -setAnisoFilter to setup texture filtering	2017-07-21 12:10:37 +03:00
kgv	79f4f03618	0026122: Visualization, TKOpenGl - clipping and capping is broken when ffp is disabled on Linux ... OpenGl_Clipping - do not setup clipping planes using FFP when it is disabled. OpenGl_ShaderManager - apply 2d texture coordinates transformation in GLSL programs. OpenGl_Context::SetTextureMatrix() - move texture matrix assignment from OpenGl_Workspace::setTextureParams() to OpenGl_Context. Add test case demo/samples/dimensionsglsl with FFP turned OFF. Add test case v3d/glsl/texture_trsf applying texture transformation. Small correction of test case for issue CR26122	2015-10-22 10:28:59 +03:00
