gl-flags
Easily change and access your WebGL flags set by gl.enable
/gl.disable
with
minimised overhead. This package transparently adds a caching layer to these
functions, providing a more convenient API, smoothly interoperating with
other libraries unaware of gl-flags
, and only requiring to read from the GPU
once for each parameter on creation.
Usage
flags = glFlags(gl)
Creates a new flags
instance attached to gl
, which is a
WebGLRenderingContext
.
flags.FLAG_NAME
Returns a boolean value reflecting whether gl.FLAG_NAME
is enabled or not.
For example, the following:
var flags = glflagsBLEND = trueflagsCULL_FACE = true
Is equivalent to this:
glgl
You can access each property without needing to hit the GPU either, so you can easily toggle flags temporarily without effecting global state like so:
var previousBlend = flagsBLENDflagsBLEND = true// drawing APIflagsBLEND = previousBlend
Parameters are only changed if their state has changed.
