使用画布three.js使用数据创建纹理

Question

I am relatively new to Three.js and trying to create a texture from the data in another canvas.

To be more specific - I intend to use Heatmap.js to obtain a heat map. The heat-map is returned in another canvas. I would then like to use this heatmap as a texture on my scene.

Any ideas on how to go about doing this ?

I tried to create the texture out of that canvas but getting a black texture.

Answer 1

I had a similar problem with black textures. This may help:

// create texture from canvas
var texture = new THREE.Texture(canvas);
// my solution:
texture.needsUpdate = true
