Creating more speed sensation using motion blur.

MOTION BLUR TECHNIQUES

Racer has multiple motion blurring options; car wheels can have multiple blurred models, and fullscreen motion blurring exists since v0.5.3 beta 6. Notice that wheel blurring comes relatively for free if you use full-screen motion blur, although currently the wheel blurring itself can look better.

Fullscreen Motion Blur

The method used is to use FBO's (Frame Buffer Objects). These are required anyway for fullscreen postprocessing GPU shaders. See also the page on fullscreen shaders for more information on motion blur.

• set racer.ini's renderer.motion_blur.method to 4
• set renderer.motion_blur.blur_alpha to something like 0.5. This is the amount of mixing between the new frame and the old frame (in the framebuffer). Higher values (towards 1) mean more blur, although too much just probably gives more headaches.
• empty renderer.motion_blur.fs_filter1/fs_filter2
