Learning WebGL is difficult.
What I’ve understood so far, after 3+ months experience with WebGL? stackgl is a set of tools somewhere in-between raw WebGL API and graphic frameworks like three.js. But the purpose of these tools is not completely clear.
I guess the motive behing things like gl-shader
Conceived as an analog to browserify, the idea to include dependencies tree applied to shaders seemed promising. But reality of shaders is different. Examples:
-
Dynamically set precision of floats:
precision ${this.precision} float -
Define constants through options:
const int WIDTH = ${this.width} -
Set precision declaration once for all shaders
-
Include part of external glslify module instead of importing it
-
Sourcemap lines are messed up - debugging is impossible
-
deps tree or dup resolving is not really necessary - shader code is rarely too huge, it is often linear.
Guess I should come up with something like debugger
debug(gl, source);
which enables log() command
