Spent a ton of time a while back trying to finally really understand the difference between different projections to render a 3D scene onto a 2D image. Ultra common ones being:
|Perspective||All (light) lines to a point|
|Orthographic||All lines parallel to a plane|
|Isometric||Special case of orthographic, all axes equal|
Wikipedia has some diagrams and way more info, but the best diagrams I’ve seen are in computer graphics textbooks.
What’s funny is that I often still have a hard time telling which is used. E.g., I just finished playing Tunic, and just trying to recall the visuals, I can’t tell whether it’s a perspective or orthographic projection.
Here’s a recent test scene trying both ways.
I’m also curious which the voxel community favors.
