Our first assignment asked us to draw simple shapes using WebGL. For this particular project I drew a simple square and triangle. Here is a screen shot of my work.
If you have a WebGl capable browser, then follow the link and you can test it yourself. Make sure you view source on the page. I heavily commented the code.
Here are the three files you need to run this lesson.
lesson1.html
sylvester.js
glUtils.js
How can i write this code in a stand alone java script file
#ifdef GL_ES
precision highp float;
#endif
void main(void) {
gl_FragColor = vec4(1.0, 1.0, 1.0, 1.0);
}
attribute vec3 aVertexPosition;
uniform mat4 uMVMatrix;
uniform mat4 uPMatrix;
void main(void) {
gl_Position = uPMatrix * uMVMatrix * vec4(aVertexPosition, 1.0);
}
and then call it again
