I have something like the below (as a working but not-generic stopgap measure)..
How would you suggest making it generic so that I can use any size of float? Or, should I make it like really generic and use ::Zero
too?
pub fn write_scale_matrix(width:f64, height:f64, depth:f64, out:&mut [f32]) {
out[0] = width as f32;
out[1] = 0.0;
out[2] = 0.0;
out[3] = 0.0;
out[4] = 0.0;
out[5] = height as f32;
out[6] = 0.0;
out[7] = 0.0;
out[8] = 0.0;
out[9] = 0.0;
out[10] = depth as f32;
out[11] = 0.0;
out[12] = 0.0;
out[13] = 0.0;
out[14] = 0.0;
out[15] = 1.0;
}
