====== BumpMap Material (TGorillaBumpMapMaterialSource) ======


The **TGorillaBumpMapMaterialSource** (TGorillaBumpMapMaterial) is inherited from the [[normalmap-material|TGorillaNormalMapMaterialSource]], supports multiple light sources and extends normal-mapping functionality by a specular texture map for better specular color results by: **GORILLA_GLSL_DEFINE_BUMP**

{{:1.0.0:normalmapping.jpg?nolink|}}

//__Hint:__ Due to historical development of Gorilla3D this is called BumpMap-Material, even if this terminologically not fully correct.//

By this material a new **SpecularMap** texture property is provided.

===== Example =====

<file pascal>
uses
  Gorilla.Material.BumpMap;
  
var FBumpMapMaterial : TGorillaBumpMapMaterialSource;

FBumpMapMaterial:= TGorillaBumpMapMaterialSource.Create(GorillaViewport1);
FBumpMapMaterial.Parent := GorillaViewport1;
FBumpMapMaterial.Texture.LoadFromFile('brick-c.jpg');
FBumpMapMaterial.NormalMap.LoadFromFile('brick-n.jpg');
FBumpMapMaterial.SpecularMap.LoadFromFile('brick-s.jpg');

FBumpMapMaterial.NormalIntensity := 1.0;
