Lightweight Java Gaming Library / Re: It seems like my rendering is wrong but im not sure why

Read this: https://github.com/JOML-CI/JOML/wiki/Common-Pitfalls#angles-are-always-in-radians

Currently, you are passing 90 radians to Matrix4f.perspective()

made these getters and replaced camera.Zoom with camera.getZoom
i also replaced other things where necessary which is really only this:

Code: [Select]

front.x = (Math.cos(getYaw()) * Math.cos(getPitch()));
front.y = Math.sin(getPitch());
front.z = (Math.sin(getYaw()) * Math.cos(getPitch()));
It was an improvement of the white pixels being shown roughly 3 seconds instead of 1

so that wasnt the entire solution

Lightweight Java Gaming Library / It seems like my rendering is wrong but im not sure why

« Last post by coolian on September 20, 2020, 15:15:33 »

Camera:https://pastebin.com/Vb1xFir6
Main:https://pastebin.com/wMchBSbV
shaders:https://pastebin.com/UmQyRFNs

The problem is that i should see a model of a dragon befor i added the camera that worked about fine.
now i can only see some white pixels that disapear really fast even when i keep setting the position of the camera to 0 -3 0
this means that something is wrong with my rendering.
I would appreciate some help

somewhere in here https://pastebin.com/Vb1xFir6
is still an error but it propably is'nt related to this question.

Code: [Select]

Matrix4f viewMatrix = new Matrix4f();
Vector3f pos = Position;
Vector3f up = Up;
Vector3f front = Front;
viewMatrix = viewMatrix.lookAt(pos, pos.add(front), up);
that is done because im pretty sure doing

Code: [Select]

viewMareiy.lookAt(Position, Position.add(Front), Up);would change the Position vector which for creating the view matrix i obviously dont want.

There is absolutely zero difference between your first code and the second line... You just assign the same instance to new local variables, that still point to the same object instance.
Therefore, you still modify the vector stored in Position/pos. You can do something like:

Code: [Select]

viewMareiy.lookAt(Position, Position.add(Front, new Vector3f()), Up);
in order to store the addition result in a new vector object.

Also, please read this first: https://github.com/JOML-CI/JOML/wiki/Common-Pitfalls#methods-without-a-dest-parameter-modify-this-and-return-this

Ok i just gotta not do Math.toRadians();

Code: [Select]

front.x = (float) (Math.cos(Math.toRadians(Yaw)) * Math.cos(Math.toRadians(Pitch)));
front.y = (float) Math.sin(Math.toRadians(Pitch));
front.z = (float) (Math.sin(Math.toRadians(Yaw)) * Math.cos(Math.toRadians(Pitch)));
Front = front.normalize(Front); those calculations are the problem it seems they mess up x

The FRONT Constant gets messed up but idk where because its not when it gets created

I have  a Camera class:https://pastebin.com/ykmAj8zv
and the xyz components of the Vectors from joml get set to nan for some reason in any other class the only thing hats being done to it is telling the camera to process keypresses mousescroll and mouse position data aswell as getting the view matrix, getting the zoom and creating it
the reason things like

Code: [Select]

Matrix4f viewMatrix = new Matrix4f();
Vector3f pos = Position;
Vector3f up = Up;
Vector3f front = Front;
viewMatrix = viewMatrix.lookAt(pos, pos.add(front), up);that is done because im pretty sure doing

Code: [Select]

viewMareiy.lookAt(Position, Position.add(Front), Up);would change the Position vector which for creating the view matrix i obviously dont want.
Why do all the Vectors get messed up.
