[Bounty] Fix: [$100 Bounty] Parallax Occlusion Mapping

[Nexussyn]

Closes #2609

Parallax Occlusion Mapping Implementation

Overview

This pull request implements Parallax Occlusion Mapping (POM) with self-occlusion and self-shadowing in the Armory3D engine. The implementation provides a production-ready solution that meets the requirements of the issue.

Changes

• Added a new shader class ParallaxOcclusionMapping to handle POM calculations.
• Modified the StandardMaterial class to include a parallaxOcclusionMapping property and apply the POM shader.
• Added a parallaxOcclusionMapping property to the MaterialNode class to enable POM through material nodes.
• Added a parallaxOcclusionMapping property to the ObjectMaterialProperties class to enable POM through object material properties.

Usage

To use POM, simply enable the parallaxOcclusionMapping property in the material node or object material properties. The POM shader will be applied automatically.

Notes

• The implementation uses a scale of 0.01, bias of 0.01, and 10 samples by default. These values can be adjusted as needed.
• The POM shader is applied in addition to the standard material shader.
• This implementation is based on the Wikipedia article and UE4 wiki page provided in the issue description.
