Summary0023817: Marker primitives presentation in TKOpenGl should be redesigned
DescriptionThere are several issues with current implementation of markers:
- Displaying of marker set is extremely slow even for GL_POINTS presentation.
- Extensive usage of display lists functionality deprecated in recent OpenGL versions.
- Markers primitive is logically subset of Primitive Arrays however OpenGl_PrimitiveArray currently supports only GL_POINTS presentation.
- OpenGL device memory for display lists is managed outside from common logic (within deprecated OpenGl_Display class).
TagsNo tags attached.
