My shader Expects float4 for camera position.

[The_Glitch]

In my shader callback I can get the cameras position but it only return a 3d vector but my shader also uses the .w for the last floating point so float4 instead of float3.

Code: Select all

 
 
            core::vector3df pos = device->getSceneManager()->
            getActiveCamera()->getAbsolutePosition(); // returns float3
               
           f32 camera[4] = { pos.X, pos.Y, pos.Z, 1.0f };
        services->setVertexShaderConstant(EYE, reinterpret_cast<f32*>(&camera), 4);
 
 

Does this seem okay?

No. Drop the cast and the '&'. In 'C', the name of an array is a pointer.

I'm using shader-pipeline so I believe shader callback is different.

Do you mean

Code: Select all

&camera

???

[mongoose7]

services->setVertexShaderConstant(EYE, camera, 4);

Okay I see what you mean thanks mongoose7.
