Detailed Description

VertexStreamAttribute is used to specify the vertex attribute for drawing, which is correspondent to glVertexAttribPointer(GLuint index, GLint size, GLenum type, GLboolean normalized, GLsizei stride, const GLvoid* ptr).

_semantic -> index _size -> size _type -> type _normalize -> normalized _offset is used to compute the start offset in a interleaved array, take a V3F_C4B_T2F array, offset of vertex will be 0, offset of color would be 0 + sizeof(float) * 3 = 12, offset of texture coord would be 12 + sizeof(char) * 4 = 16.

Constructor & Destructor Documentation

VertexStreamAttribute ( int  offset, int  semantic, int  type, int  size  )

inline

Constructor The offset of the attribute.

The semantic (Position, Texcoord, Color etc) of attribute. The type of attribute, could be GL_FLOAT, GL_UNSIGNED_BYTE etc. Describe how many elements of type in the attribute.

var VertexStreamAttribute ( var  offset, var  semantic, var  type, var  size  )

inline

Constructor The offset of the attribute.

The semantic (Position, Texcoord, Color etc) of attribute. The type of attribute, could be GL_FLOAT, GL_UNSIGNED_BYTE etc. Describe how many elements of type in the attribute.

local VertexStreamAttribute ( local  offset, local  semantic, local  type, local  size  )

inline

Constructor The offset of the attribute.

The semantic (Position, Texcoord, Color etc) of attribute. The type of attribute, could be GL_FLOAT, GL_UNSIGNED_BYTE etc. Describe how many elements of type in the attribute.

VertexStreamAttribute ( int  offset, int  semantic, int  type, int  size, bool  normalize  )

inline

Constructor The offset of the attribute.

The semantic (Position, Texcoord, Color etc) of attribute. The type of attribute, could be GL_FLOAT, GL_UNSIGNED_BYTE etc. Describe how many elements of type in the attribute. If true, the data will be normalized by deviding 255.

var VertexStreamAttribute ( var  offset, var  semantic, var  type, var  size, var  normalize  )

inline

Constructor The offset of the attribute.

The semantic (Position, Texcoord, Color etc) of attribute. The type of attribute, could be GL_FLOAT, GL_UNSIGNED_BYTE etc. Describe how many elements of type in the attribute. If true, the data will be normalized by deviding 255.

local VertexStreamAttribute ( local  offset, local  semantic, local  type, local  size, local  normalize  )

inline

Constructor The offset of the attribute.

The semantic (Position, Texcoord, Color etc) of attribute. The type of attribute, could be GL_FLOAT, GL_UNSIGNED_BYTE etc. Describe how many elements of type in the attribute. If true, the data will be normalized by deviding 255.
