Immediate Mode Replacement Tasks

What and how to do it

See Immediate Mode Replacement call for help.

What exactly needs to be recoded? Any calls to glBegin, glEnd, glVertex, glColor, glNormal, glTexCoord, glRect.

What does not need to be recoded?
State-setting functions such as glEnable, glDisable, glPointSize, glBlendFunc, glDepthFunc, glDepthMask, glColorMask …
glLineWidth is also legacy, but let’s not worry about that just yet!

Utility functions such as UI_ThemeColor and fdrawline call the old GL functions, so find ways to draw without these. Use the new immUniformThemeColor instead, and draw lines with immVertex immVertex.

Help Wanted - Game Engine

The UPBGE team plans to merge their work into Blender2.8 so we should leave these files alone.

ImageRender.cpp
KX_Dome.cpp
RAS_2DFilterManager.cpp
RAS_OpenGLRasterizer.cpp
RAS_StorageVA.cpp
RAS_StorageVBO.cpp

Help Wanted - Intern

Notes

(write down any false positive that may come up from the grep query)

area.c - it needs to be revisited once the MatrixAPI supports 2D (see 31a21135)
wm_playanim.c (requires decision about bg mode access to gpu) (ianwill)
uvedit_draw.c (still has one UI_ThemeColor call because of unconverted DM callback) (LucaRood)

Is a file done?

To check if a file is done use the following script:

https://github.com/dfelinto/immediate-mode-query/blob/master/query

It basically uses the query below. Both will be kept updated if we decide to expand the query.
