Error: GL ERROR :GL_INVALID_OPERATION : glTexImage2D

Hi,

We are developing a kind of 3D graph. We are using Angular with Three-full NPM (https://github.com/Itee/three-full). We are implementing the Nodes as particles and we are drawing them with shaders.

Code bellow of the post*

That works pretty good in the web browser (Mozilla and Chromium) with Linux environment but when we test it in the web browser with Windows environment, shaders crash and the drawing of the nodes is not done (appear that error message).

3d2
3D Graph in Windows environment

We search what the error means but there’s no clarifying information. The point is that if we use LineMaterial and not Shaders with RawShadersMaterial then it works nice, but with a reduction in performance. Is there any technical issue in Windows System that make it happens? How we can solve it? We try to comment everything about textures but it generate the same error. It seems that the problem in relate especially with the use of both Shaders.

Any chances to provide a live example that demonstrate the issue?

Hi, Mugen
There it is: https://jsfiddle.net/dmartmilln/a48by2vr/
It’s a simple example of a Sphere in center with different nodes arround it.
Thank you.

Please add ``` before and after your code to format it.

This example is very complicated though. Can you strip down the shader / buffers until you render something with no issues?

pailhead · August 9, 2018, 9:13am

What are you doing with USE_MAP? Can you try commenting out that define? I’m not sure why you would want it and especially in a RawShaderMaterial, i wouldn’t at all be surprised if this triggers some phantom limbs or something.

Mugen87 · August 9, 2018, 9:48am

What I see at your code is that you are not interleaving your geometry data correctly.

const positionBuffer = new Float32Array(new ArrayBuffer(particles * 12));
const colorBuffer = new Uint8Array(new ArrayBuffer(particles * 3));

Creating a new array buffer for each attribute will not interleave the data in memory. Have a look at the following example in order to see the correct approach. You have to use a single array buffer for all data.

https://threejs.org/examples/webgl_buffergeometry_points_interleaved

Unfortunately, I’m using macOS so I can’t reproduce the mentioned warning. One thing you should avoid is the usage of the following code since it has no effect for RawShaderMaterial:

defines: {
   USE_MAP: true
},

pailhead · August 9, 2018, 9:02pm

Yeah the interleaved buffer thing seemed a bit confusing, but i figured if it rendered what you expected it somehow worked. I’m really really curious about the USE_MAP.
