Abstract class defining the interface for objects that buffer geometry for later rendering.
Definition: GeometryBuffer.h:44
Texture * getActiveTexture() const
Return a pointer to the currently active Texture object. This may return 0 if no texture is set.
RenderEffect * d_effect
RenderEffect that will be used by the GeometryBuffer.
Definition: GeometryBufferBase.h:125
void setTranslation(const Vector3f &t)
Set the translation to be applied to the geometry in the buffer when it is subsequently rendered.
void performBatchManagement()
perform batch management operations prior to adding new geometry.
uint getVertexCount() const
Return the total number of vertices currently held by this GeometryBuffer object.
type to track info for per-texture sub batches of geometry
Definition: GeometryBufferBase.h:96
OpenGLTexture * d_activeTexture
last texture that was set as active
Definition: GeometryBufferBase.h:105
void setActiveTexture(Texture *texture)
Set the active texture to be used with all subsequently added vertices.
void setClippingActive(const bool active)
Set whether clipping will be active for subsequently added vertices.
void setClippingRegion(const Rectf ®ion)
Set the clipping region to be used when rendering this buffer.
std::vector< GLVertex > VertexList
type of container used to queue the geometry
Definition: GeometryBufferBase.h:111
void setRotation(const Quaternion &r)
Set the rotations to be applied to the geometry in the buffer when it is subsequently rendered.
Main namespace for Crazy Eddie's GUI Library.
Definition: arch_overview.dox:1
Class to represent rotation, avoids Gimbal lock.
Definition: Quaternion.h:69
Texture implementation for the OpenGLRenderer.
Definition: RendererModules/OpenGL/Texture.h:45
void setRenderEffect(RenderEffect *effect)
Set the RenderEffect to be used by this GeometryBuffer.
Rectf d_clipRect
rectangular clip region
Definition: GeometryBufferBase.h:115
structure that is used to hold details of a single vertex in 3D space.
Definition: Vertex.h:42
OpenGLRendererBase * d_owner
OpenGLRendererBase that owns the GeometryBuffer.
Definition: GeometryBufferBase.h:103
RenderEffect * getRenderEffect()
Return the RenderEffect object that is assigned to this GeometryBuffer or 0 if none.
void reset()
Clear all buffered data and reset the GeometryBuffer to the default state.
Definition: GlmPimpl.h:37
mat4Pimpl * d_matrix
model matrix cache - we use double because gluUnproject takes double
Definition: GeometryBufferBase.h:127
Abstract base class specifying the required interface for Texture objects.
Definition: Texture.h:54
BatchList d_batches
list of texture batches added to the geometry buffer
Definition: GeometryBufferBase.h:109
OpenGL based implementation of the GeometryBuffer interface.
Definition: GeometryBufferBase.h:53
Quaternion d_rotation
rotation quaternion
Definition: GeometryBufferBase.h:121
uint getBatchCount() const
Return the number of batches of geometry that this GeometryBuffer has split the vertices into.
void appendGeometry(const Vertex *const vbuff, uint vertex_count)
Append a number of vertices from an array to the GeometryBuffer.
internal Vertex structure used for GL based geometry.
Definition: GeometryBufferBase.h:88
bool d_clippingActive
whether clipping will be active for the current batch
Definition: GeometryBufferBase.h:117
void appendVertex(const Vertex &vertex)
Append a single vertex to the buffer.
void updateMatrix() const
update cached matrix
std::vector< BatchInfo > BatchList
type of container that tracks BatchInfos.
Definition: GeometryBufferBase.h:107
bool d_matrixValid
true when d_matrix is valid and up to date
