Canvas inspector ignores instanced arrays
I'm playing with ANGLE_instanced_arrays and three.js. The canvas inspector reports 3 drawcalls where there should be 5. After the first clear call i see the instanced stuff drawn in the preview buffers but the only thing listed are 'regular' calls. Ie. when i click on the snapshot it shows the geometry drawn in the reported call but the instanced stuff is already in there without it being mentioned anywhere (2 missing draw calls).

(Sample code [& not that I'd be able to do anything with it]?)

Re: Canvas inspector ignores instanced arrays
There really isn't any special code i think. I use three.js so i'd have to consult the source, but also taking the bare essentials from here should replicate

Result, this drawcall does not exist in the inspector. Any other does.
Wow, it's been almost a year

Code: Select all
var ext = gl.getExtension("ANGLE_instanced_arrays") //get extension?
ext.drawElementsInstancedANGLE(gl.TRIANGLES, indexCount, gl.UNSIGNED_SHORT, 0, instanceCount) //draw
