Hajime Hoshi	107dfe5074	graphics: Improve Set speed ... On GopherJS, copying a struct is very heavy. This change avoids copying (color) structs when possible.	2019-01-14 04:25:43 +09:00

Hajime Hoshi	1e1f309a1c	shareable: Add Fill ... Before introducing Fill, filling an image with a solid color was implemented by ReplacePixels. When an offscreen image is used, the offscreen image is not fully cleared or filled with a color and out of (0,0)-(width,height) region. This causes a glitch thin line on mobile platforms. This change adds (*shareable.Image).Fill to fill the whole framebuffer region of the image.	2019-01-13 02:12:47 +09:00

seebs	74e204d952	graphics: Speed up DrawTriangles (#723) ... DrawTriangles is expensive and slow because of massive memory allocation and garbage collection costs. This patch moves from ~47TPS on my laptop (with ~24k triangles) to 60TPS. The first part is just allocating the right size of vertex buffer up front; that got to about 55TPS. The second part replaces the frequent allocations of []float32 in Vertex() calls with writing the desired values into a provided destination slice. Time spent in drawing triangles for 1,000 frames: 13.07s baseline 11.09s preallocate whole buffer to avoid resizing 6.13s use new PutVertex function This might need some cleanup, but I think it's good evidence that the design change is viable.	2018-10-31 10:53:17 +09:00
