Rendering flashes on the screen

Rendering flashes on the screen

Postby jobenmoe » 15 Sep 2017, 02:03

Hello,
I'm trying to index the replay of the race recordings based on flashes. I want to programatically render a flash every other frames of the race. Can someone guide me on how I could do that? I'm already familiar with the GL32_draw2DRectangle function for drawing image but I need to know How I can draw flashes every other frame. I'm not too familiar with the structure of the code so it would help alot if someone could help with this.

Best,
Jason

Hi,

I guess it depend whether you envision the flash as being a light in the 3D world, or a GUI overlay.

For an in-engine flash done with lighting I'm probably not the best person to ask. This would likely involve changs to shaders

If you envision it as an overlay, take a look at states_screens/race_gui.cpp, that's where all the stuff is drawn.

Oh I forgot... we already have a similar effect used to render lightning, take a look at graphics/post_processing.cpp, "renderLightning"
