When trying to use the `map: texture` with a new `THREE.Texture(canvas)

i'm trying to apply the texture from new THREE.Texture(canvas) to the PointsMaterial, but it's not working as expected. The canvas appears on the top right corner, however, only white points are visible in the CubeGeometry.

    var texture = new THREE.Texture( canvas );
    texture.needsUpdate = 1;

Surprisingly, when I use the texture from 

new THREE.TextureLoader().load( "snowflake5.png" )
, everything works fine.

Can anyone point out where I may have gone wrong?

Answer №1

When creating a texture from a canvas element, ensure to set the needsUpdate flag to true with this code snippet:

    var texture = new THREE.Texture( canvas );
    texture.needsUpdate = true;

Alternatively, you can simplify by using this pattern which automatically sets the needsUpdate flag for you:

    var texture = new THREE.CanvasTexture( canvas );

Regarding the issue in your code, it is because of this comparison:

true === 1 // false

This information applies to three.js version r.85.
