Simple Dynamic Shadows with Normal Mapping Tutorial

Reference: https://learnopengl.com/Advanced-Lighting/Shadows/Shadow-Mapping

Prerequesites: Simple Dynamic Shadows

Note: This is directional shadows ONLY, no point or spotlight shadows

New Concepts: Depth buffer

The different steps with Simple Dynamic Shadows are listed below:

We attach a normal map texture onto our shadow pass material. We enable a tangent attribute for our second pass In the shadow vertex shader we calculate a new Tangent-bitangent-normal(TBN matrix) In the shadow frag shader we calculate diffuse value using dot(light direction, normal) For the second pass we manually set the texture location to 4
