Simplification of the code by using glm and reducing templates

[FelixTUD]

BREAKING CHANGES TO THE ISAAC INTERFACE

• Removed templates for IsaacVisualization class changes expected types to be isaac internal types like isaac_float3
• isaac now expects the render volume to be 3D, the 2D implementation wasn't working before anyway
• Guaranteed internal types simplify the code structure
• Removal of unnecessary templates, as they already had many requirements at the type, which often resulted in complicated compiler errors if they were not met

IMO result is not required anymore and you can return value directly.

@FelixTUD PLease check this comment!

[psychocoderHPC]

Is it possible to use the upstream version of glm for issac. If I remember correctly some changes were required to support CUDA.

[psychocoderHPC]

Please add glm to the requirements in INSTALL.md. If a minimal version is required add this information too.

[FelixTUD]

Yes for CUDA a recent glm upstream version works without adjustments, only the future hip support needs some changes

[FelixTUD]

@psychocoderHPC the requested changes are integrated

[psychocoderHPC]

Here I am not sure if you can return value only. Value is a scalar. How is the implementation if you cast isaac_float to isaac_float_dim <3>? Is the scalar only assigned to .x or to all 3 members.

[FelixTUD]

It is fixed now, as feature_dim is set to 1 the type is isaac_float_dim <1> and there is no implicit conversion from isaac_float to isaac_float_dim <1>
