Detailed Description

Vertex data representing a 3D graphical object.

Member Typedef Documentation

◆ attribute_component_data_type

using gdk::webgl1es2_model::attribute_component_data_type = GLfloat

type that must be used to populate vertex data buffers. All GLES2 attrib types have a float based component type. (float, float vec2, float mat etc)

Member Enumeration Documentation

◆ PrimitiveMode

enum gdk::webgl1es2_model::PrimitiveMode

strong

Determines the primitive type used at the primitive assembly stage.

Enumerator
Points	Every vertex is replaced with a point at the primitive assembly stage.
Lines	Every two verticies define a line.
LineStrip	Same as lines except the last vertex of the last defined line serves as the first vertex of the line currently being defined
LineLoop	Same as LineStrip except an additional line is defined between the last and first vertex.
Triangles	Every 3 verticies define a triangle.
TriangleStrip	Every vertex after the first three define a new triangle.
TriangleFan	Same as Triangle strip except draws in a "fan shape" (???) TODO: find & document better explanation

◆ Type

enum gdk::webgl1es2_model::Type

strong

Hint to the graphics device about how the vertex data will be used.

Enumerator
Dynamic	The data store contents will be modified repeatedly and used many times.
Static	The data store contents will be modified once and used many times.
Stream	The data store contents will be modified once and used at most a few times.

Member Function Documentation

◆ bind()

void gdk::webgl1es2_model::bind ( const webgl1es2_shader_program & aShaderProgram ) const

strong association with draw. If draw is on this instance is not called after bind() has not been called before draw, the behaviour will be unintended

Binds this vertex data to the pipeline, enables attributes on the currently used shaderprogram
