Class
CoglPrimitive
Description [src]
final class Cogl.Primitive : GObject.Object
{
/* No available fields */
}Functions for creating, manipulating and drawing primitives.
Constructors
cogl_primitive_new
Combines a set of CoglAttributes with a specific draw mode
and defines a vertex count so a CoglPrimitive object can be retained and
drawn later with no addition information required.
cogl_primitive_new_p2
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary CoglAttributeBuffer storage, describe the position
attribute with a CoglAttribute and upload your data.
cogl_primitive_new_p2c4
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary CoglAttributeBuffer storage, describe the position
and color attributes with CoglAttributes and upload
your data.
cogl_primitive_new_p2t2
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary CoglAttributeBuffer storage, describe the position and
texture coordinate attributes with CoglAttributes and
upload your data.
cogl_primitive_new_p2t2c4
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary CoglAttributeBuffer storage, describe the position, texture
coordinate and color attributes with CoglAttributes and
upload your data.
cogl_primitive_new_p3
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary CoglAttributeBuffer storage, describe the position
attribute with a CoglAttribute and upload your data.
cogl_primitive_new_p3c4
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary CoglAttributeBuffer storage, describe the position
and color attributes with CoglAttributes and upload
your data.
cogl_primitive_new_p3t2
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary CoglAttributeBuffer storage, describe the position and
texture coordinate attributes with CoglAttributes and
upload your data.
cogl_primitive_new_p3t2c4
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary CoglAttributeBuffer storage, describe the position, texture
coordinate and color attributes with CoglAttributes and
upload your data.
cogl_primitive_new_with_attributes
Combines a set of CoglAttributes with a specific draw mode
and defines a vertex count so a CoglPrimitive object can be retained and
drawn later with no addition information required.
Functions
cogl_primitive_texture_set_auto_mipmap
Sets whether the texture will automatically update the smaller mipmap levels after any part of level 0 is updated. The update will only occur whenever the texture is used for drawing with a texture filter that requires the lower mipmap levels. An application should disable this if it wants to upload its own data for the other levels. By default auto mipmapping is enabled.
Instance methods
cogl_primitive_copy
Makes a copy of an existing CoglPrimitive. Note that the primitive
is a shallow copy which means it will use the same attributes and
attribute buffers as the original primitive.
cogl_primitive_draw
Draws the given primitive geometry to the specified destination
framebuffer using the graphics processing state described by pipeline.
cogl_primitive_get_n_vertices
Queries the number of vertices to read when drawing the given
primitive. Usually this value is implicitly set when associating
vertex data or indices with a CoglPrimitive.
cogl_primitive_set_n_vertices
Specifies how many vertices should be read when drawing the given
primitive.
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
