The performance degradation in immediate mode is expected. If I
remember correctly, the LIC algo renders the geometry twice, once to
produce the standard rendering and second time to generate projected
vector fields which are then processed to generate the LIC image that
is then finally blended
Hi Utkarsh,
The issues may be due to my misuse of your design :). I have had
immediate mode disabled for quite some time as it had greatly improved
performance. however this seams to be a major factor in the huge memory
bloat when using LIC rep.
When I enabled immediate mode, memory usage
I doubt it's part of the design so to speak :). My suspicion is some
OpenGL buffers are not being released or something of that nature.
I'll try to track it down.

Hi,
I am seeing some pretty astounding memory usage
