Oriented projectiles keep facing camera

QUESTION

Oriented projectiles keep facing camera

Asked 2021-Oct-16 at 15:17

I'm trying to render a 2d image that represent a projectile in a 3d world and i have difficulty to make the projectile face the camera without changing its direction. Im using JOML math library.

my working code to orient the projectile in his direction

Since you are using JOML, you can massively simplify your whole setup.

Let's assume that:

projectilePosition is the position of the projectile,
targetPosition is the position the projectile is flying at/towards, and
cameraPosition is the position of the "camera" (which we ultimately want the projectile to face)

We will also assume that the local coordinate system of the projectile is such that its +X axis points along the projectile's path (like how you depicted it) and the +Z axis points away from the projectile towards the viewer when the viewer is "facing" the projectile. So, the projectile itself is defined as a quad on the XY plane within its own local coordinate system.

What we must do now is create a basis transformation that will effectively transform the projectile such that its X axis points towards the "target" and its Z axis points "as best as we can" towards the camera.

This is very reminiscent of what we know as the "lookAt" transformation in OpenGL. And in fact, we are just going to use that. However, since the common "lookAt" is the inverse of what we wanted to do, we will also just invert it.

So, all in all, your complete model matrix/transformation for a single projectile will look like this (in JOML):
