Christopher Willis-Ford	4fc42ca00a	Added a TODO regarding a texturing issue ... The current fragment chader contains non-uniform control flow for determining the texture coordinates to use with `texture2D()`. The spec says that this can cause undefined behavior; in my case I see a "sparkle" of wrong pixels near primitive edges. See: https://www.opengl.org/wiki/Sampler_%28GLSL%29#Non-uniform_flow_control	2016-05-17 14:10:51 -07:00
Christopher Willis-Ford	dbe3f1370b	Draw a squirrel ... This change introduces the Drawable class, which corresponds to a Scratch sprite or clone. It supports setting its "skin" (corresponding to a Scratch costume) by md5+extension, but currently only supports bitmap skins. Drawables can be created, destroyed, and otherwise manipulated by ID through the renderer.	2016-05-17 13:52:37 -07:00
Christopher Willis-Ford	51e17c57a9	Establish initial structure, create demo.html ... So far this does nothing but clear the screen to magenta, but it's a start.	2016-05-13 11:29:51 -07:00
