[Qgis-developer] What about OpenGL renderding ?

[kimaidou]

Hi all,

Preamble : I am not a QGIS core rendering guru, nor an opengl/webgl, etc.
one.

In web mapping contexts, major improvements are made in 2D vector rendering
speed by using WebGl technology, such as in upcoming OpenLayers 3. As a
user point of view, improvement seems huge compared to classical DOM or
more advanced CANVAS renderer.

What about using graphic card to help improve rendering performance in QGIS
? Would this help a lot, or at the contrary would this be a dead-end ?

I have seen the funding for having a multi-threaded rendering, this is why
this idea came in mind. In twitter, Pirmin told me Marco made some advanced
test. What were the conclusions ?
