Projects a PVector onto camera

[jeremydouglass]

I’m not seeing Camera.project in the three.js documentation, so I’m not totally clear on what the function does – three.js docs – can you link to the documentation?

Edit – found it: Vector3.project(): three.js docs

and

mrdoob/three.js/blob/master/src/math/Vector3.js#L315-L319

I think perhaps you should look at the reference

Reference

and specifically the Camera section functions and the Matrix functions, such as:

camera() / Reference

perspective() / Reference

applyMatrix() / Reference

Is your question related to this?

Planar equation from camera image

Hi, I’m new to the forum. I’ve appended a jpeg to illustrate my question, sorry for its amateurish appearance. My question: in the given setup, how do I calculate the equation of the image plane from 3 points – pp1, pp2, pp3? I understand how to solve for the 3D plane in real world points that are behind the projected points but not from its projected points. [quessetup]
