    copied!<p>Here is my issue. I'm rendering axis alligned cubes that are all the same size. I created an algorithm that rendered around the player like this:</p> <pre><code>****** ****** ***p** ****** ****** </code></pre> <p>While this does work, the player does not see this whole radius. I know the player's rotation angle on the Y, so I was hoping to modify my algorithm based on this so that it would only render about, what the player can see more or less.</p> <pre><code>SetPlayerPosition(); float yrotrad; yrotrad = (Camera.roty / 180 * 3.141592654f); PlayerPosition.x += 70 * float(sin(yrotrad)); PlayerPosition.y -= 20; PlayerPosition.z += 70 * -(float(cos(yrotrad))); collids.clear(); for(int i = 0; i &lt; 135; ++i) { for(int j = 0; j &lt; 50; ++j) { for(int k = 0; k &lt; 135; ++k) { if(!CubeIsEmpty(PlayerPosition.x + i, PlayerPosition.y + j, PlayerPosition.z + k)) { collids.push_back(GetCube(PlayerPosition.x + i, PlayerPosition.y + j, PlayerPosition.z + k)); } } } } </code></pre> <p>Basically, my original algorithm would just subtract 70 from the players location, and render the square that is 70 in size. So I tried to multiply these by the sin and cos os the Y rotation but it did not work. I'm sure this is possible, I just think i'm missing something. How could I achieve my goal of only rendering ~what the player sees.</p> <p>Thanks</p> <p>Just as a note, I tried frustrum culling and this got too slow, I'd rather this which works no matter how many cubes I have</p> <p>instead of rendering the above id like it to only, ex if the player is facing -></p> <pre><code>...... **** ...... **** ......P**** ...... **** </code></pre>
