Squashed sphere?

Blitz3D Forums/Blitz3D Programming/Squashed sphere?

I have a sphere and a camera the camera is set back into the z plane a little and up on the y plane a little.

When the sphere is in the middle of the screen it looks great. However when I move it to the left or right it looks squashed. ARRGH!

Why is this?

Try altering the setting for Camerazoom, this should show you what you can do with the settings:


if keydown(203) then cz#=cz-0.1
if keydown(205) then cz#=cz+0.1

BVut my camera zoom is the default - shouldn't that keep the correct perspective?

There is no "correct" camerazoom to use. It is a metter of prerference.

The distortion is perfeclty normal. You just don't notice it in real life because you cannot see what is in your peripheral vision very well. You can reduce it in the game by reducing the FOV, which ou do with camerazoom, but this reduces how wide an area you can see at once.

Consider the angle between your eye where you sit, and the edges of your monitor on your desk. Set the camera FOV to that angle, and everyhting will look nice and the proper scale too. But you won't be able to see a very large slice of your world.

I wish we'd get cheap popular VR goggles, then this wouldn't be a problem. :-)

A camera zoom of 1.6 looks best.

camerazoom seems to throw off mipmapping
