Constructors

GLVertex()

Create a gl vertex ( default 0,0,0 ) [object].

public GLVertex()

GLVertex(in Vector3, in Color?)

Create a gl vertex with given position [object] and color.

public GLVertex(in Vector3 position, in Color? color)

Parameters

position Vector3

Vertex position [object].

color Color?

Vertex color.

GLVertex(in Vector3, in Vector4?, in Vector3?, in Vector3?, in Vector2?)

Create a gl vertex with given position [object].

public GLVertex(in Vector3 position, in Vector4? rgbaColor = null, in Vector3? materialProperties = null, in Vector3? normal = null, in Vector2? textureST = null)

Parameters

position Vector3

Vertex position [object].

rgbaColor Vector4?

(Optional) Vertex color encoded in vector4 (range 0..1) as (red, green, blue, alpha).
Alpha=1 (full opaque).
Alpha=0 (full transparent). (Default: white).

materialProperties Vector3?

(Optional) Describe the strength (0..1) of the ambient, diffuse, specular light effects. (Default: ambient:0.8, diffuse:0.6, strength:0.6).

normal Vector3?

(Optional) Vertex normal [object]. (Default: zero).

textureST Vector2?

(Optional) Vertex texture mapping in the range [0,0]...[1,1].

GLVertex(in Vector3, in Vector2)

Create a gl vertex with given position [object] and texture coord.

public GLVertex(in Vector3 position, in Vector2 textureST)

Parameters

position Vector3

Vector position [object].

textureST Vector2

Texture position in the ranage [0,0]...[1,1].

Properties

EffectiveNormal

Vertex normal [local] eventually inverted if flag InvertNormal present.

public Vector3 EffectiveNormal { get; }

Property Value

Vector3

Flags

Vertex flags can used to switch some vertex feature.
By default no flags are active. GLVertexFlag

[JsonProperty]
public GLVertexFlag Flags { get; set; }

Property Value

GLVertexFlag

Index

GLVertexManager vertex index associated to this gl vertex or null if not yet registered to.

public uint? Index { get; }

Property Value

uint?

InvertNormal

Invert the normal flag ( used by Mirror(in Matrix4x4).

public bool InvertNormal { get; set; }

Property Value

bool

IsAttached

States if this vertex is already registed to a vertex manager.

public bool IsAttached { get; }

Property Value

bool

MaterialColor

Color encoded in vector4 (range 0..1) as (red, green, blue, alpha).
Alpha=1 (full opaque).
Alpha=0 (full transparent).

public Vector4 MaterialColor { get; set; }

Property Value

Vector4

MaterialProperties

Describe the strength (0..1) of the ambient, diffuse, specular light effects.

ParentFigure

Figure referencing this vertex in one of their primitive's components.
Its null if related figure not yet added to the vertex manager.

public IGLFigure? ParentFigure { get; }

Property Value

Property Value

IGLPrimitive

ParentVertexManager

Vertex manager which this object is registered to.
Before the object is added to the GLModel, therefore to the GLVertexManager, or after the object is removed from, this pointer is null.

ScreenProjectionMatrix

Signature

String signature of this vertex, used by GLVertexManager to keep a unique vertex array of GLVertexStruct.

public string Signature { get; }

Property Value

string

TextureST

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

public Vector2 TextureST { get; set; }

Property Value

Vector2

Methods

Copy()

Create a copy of this gl vertex manager object copying all relevant data except the ParentVertexManager that will default to null for copies object until added to a vertex manager.

string

ToStruct()

Create a struct representation of this vertex.
Some information used only by framework itself not pertinent to those used by the shader, such as Index are omitted.
