How to resize objects at different z-positions to exactly fit camera (width and height)?

[cream]

… I believe there was a post here published recently describing how to do this, but I can’t find it anymore. Does anyone have an idea what I’m talking about? There was also an example with cubes (red and blue I believe) stretched to fit the width and height of the camera positioned at different z-values. Thanks!

Functions to calculate the visible width / height at a given z-depth from a perspective camera

These two functions will give you the visible height and width in your scene at a given distance from a PerspectiveCamera. It’s useful if you want to create an object that is the full width / height of the scene, or want to place objects at screen edges etc. Here’s the code (ES6): const visibleHeightAtZDepth = ( depth, camera ) => { // compensate for cameras not positioned at z=0 const cameraOffset = camera.position.z; if ( depth < cameraOffset ) depth -= cameraOffset; else depth += c…

@looeee you should add it to THREE math

cool, thanks @Fyrestar! this one really ages well

It’s this topic you’re talking about, it was useful for me.

No it’s not, but thanks!
The topic I was looking for was exactly the one found by @Fyrestar.
