Looking for some help with this. It's easy code to understand.

My makeshift push/pop matrix code seems to have no effect at all, the model doesn't translate to it's position.

1   2   3   4   5

var savedMat = mat4.create();           savedMat.set(mvMatrix);              mat4.translate(mvMatrix, [model.x, model.y, model.z]);              gl.drawArrays(gl.TRIANGLES, 0, model.VertexPositionBuffer.numItems);           mvMatrix.set(savedMat);

I want the models to be drawn at their position/ and later on rotation, and not affect the mvMatrix (modelview matrix).

sudocode

1   2   3   4   5

create temp matrix set temp matrix to modelview matrix translate modelview matrix to model position draw model set modelview matrix to temp matrix

I have never worked with WebGL, but I googled 5 minutes.

1   2   3   4   5   6   7

var savedMat = mat4.create();           savedMat.set(mvMatrix);              mat4.translate(mvMatrix, [model.x, model.y, model.z]); +            gl.uniformMatrix4fv(shaderProgram.pMatrixUniform, false, pMatrix); +            gl.uniformMatrix4fv(shaderProgram.mvMatrixUniform, false, mvMatrix);              gl.drawArrays(gl.TRIANGLES, 0, model.VertexPositionBuffer.numItems);           mvMatrix.set(savedMat);

sudocode

if it doesn't work, switch the user!

Awesome, Riven! Thank you so much!  

Edit: added in another model, and made it so you can rotate the camera with left and right arrows.

Runs smoothly on my computer with Chrome 20. Really nice! However, I do see some visual glitches like flickering :S

Flickering just looks like z-fighting on two or more overlapping identical polygons to me.

And now time for something a little different: http://pso2u.com/webgl.php (It's a MS3d viewer, it will be animated later. if you get the error about DataView it means your browser don't support it yet.)

Chrome 20 on Windows 7, all I see is a black box. Opening up the Chrome console, I see this error:

webgl.php line 477: Uncaught TypeError: Cannot read property '51' of undefined

DataView is not supported in Firefox 13.  Is the only browser you can view that in Chrome?  Talk about bleeding edge.

I broke it :<
