Custom matrix projection camera

[isidisi]

Is posible to change the projection matrix of the camera to a custom matrix?

 

I want to do a 4 x 4 grid, where each tile is a render in order to later join them and obtain a bigger image... then I have to displace and scale after projection matrix in the camera to render each tile.

 

I tried with SetEntityMatrix but it seems not to set the projection matrix, only position and rotation of the camera...

 

Any help?

You would have to utilize the OpenGL API to modify the GL_PROJECTION matrix.

I tried and not works, when I do RenderWorld() Leadwerks Engine changes projection matrix with the parameters of the world's camera... is there a way to avoid this?

 

 

 

I tried adding some lines in Renderer.cpp:

float test[16]; //To check changes in projection matrix.

glMatrixMode(GL_PROJECTION);

::glLoadMatrixf(myProjectionMatrix);

::glGetFloatv(GL_PROJECTION_MATRIX, test); //Here test = myProjectionMatrix

 

// Render the scene

Wireframe( wiremode );

::glGetFloatv(GL_PROJECTION_MATRIX, test); //Here test = myProjectionMatrix

RenderWorld();

::glGetFloatv(GL_PROJECTION_MATRIX, test); //Here test != myProjectionMatrix, RenderWorld changed projection matrix before rendering :-(

The only way would be to have the commands in the engine to get/set the camera's matrices exposed.

 

Get/Set CameraProjectionMatrix

Get/Set CameraModelViewMatrix

Get/Set CameraModelViewProjectionMatrix
