To share textures between a 2D canvas and a WebGL canvas, you can follow these steps:
Here is an example code snippet to demonstrate how to share textures between a 2D canvas and a WebGL canvas:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
// Get the 2D canvas context var ctx = document.getElementById('canvas2d').getContext('2d'); // Create a WebGL context var gl = document.getElementById('webgl').getContext('webgl'); // Create a texture in WebGL var texture = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, texture); // Bind the texture with the 2D canvas gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, ctx.canvas); // Bind the texture with the WebGL canvas gl.bindTexture(gl.TEXTURE_2D, texture); |
This code snippet demonstrates how to create a texture in WebGL and bind it with both a 2D and a WebGL canvas, allowing you to share textures between the two.
