Interface IGLVertex

Namespace

SearchAThing.OpenGL.Core

Assembly

netcore-opengl-core.dll

Represent a vertex and its the base object managed by the GLVertexManager.
Primitives such as GLPoint, GLLine and GLTriangle store their vertex information using this type.
When the gl render happens ( see Render(IRenderDevice?) ) all the model vertexes are mapped to the gpu ram and figures with their vertex indexes are feed into.
Internally the GLVertexManager hold a struct projection of this object, the GLVertexStruct.

Extension Methods

Ext.PositionSignature(IGLVertex, float)

Ext.SetColor(IGLVertex, in Color)

Ext.SetColor(IGLVertex, in Vector4)

Ext.ToDxfVector3(IGLVertex)

Ext.EnsureDetached(IGLVertexManagerObject)

Ext.IsAttached(IGLVertexManagerObject)

Remarks

In order to manage operations such as addition and removal of figures with related vertexes the vertex manager doesn't allow to register a gl vertex twice, thus two figures cannot share the same gl vertex reference.
Note: Internally the vertex manager doesn't duplicate any vertex equals to other existing.

string

TextureST

Vertex texture offset ( range [0,0] to [1,1] ).

[JsonProperty]
Vector2 TextureST { get; set; }
