◆ createVertexBuffer()

HardwareVertexBufferSharedPtr Ogre::GLES2HardwareBufferManager::createVertexBuffer ( size_t  vertexSize,
size_t  numVerts,
HardwareBuffer::Usage  usage,
bool  useShadowBuffer = false 
)
virtual

Creates a vertex buffer.

Implements Ogre::HardwareBufferManagerBase.

◆ createIndexBuffer()

HardwareIndexBufferSharedPtr Ogre::GLES2HardwareBufferManager::createIndexBuffer ( HardwareIndexBuffer::IndexType  itype,
size_t  numIndexes,
HardwareBuffer::Usage  usage,
bool  useShadowBuffer = false 
)
virtual

Create a hardware vertex buffer.

Implements Ogre::HardwareBufferManagerBase.

◆ createRenderToVertexBuffer()

RenderToVertexBufferSharedPtr Ogre::GLES2HardwareBufferManager::createRenderToVertexBuffer ( )
virtual

Create a render to vertex buffer.

Reimplemented from Ogre::HardwareBufferManagerBase.

◆ createUniformBuffer() [1/2]

HardwareUniformBufferSharedPtr Ogre::GLES2HardwareBufferManager::createUniformBuffer ( size_t  sizeBytes,
HardwareBuffer::Usage  usage,
bool  useShadowBuffer,
const String name = ""

virtual

Create uniform buffer.

This type of buffer allows the upload of shader constants once, and sharing between shader stages or even shaders from another materials. The update shall be triggered by GpuProgramParameters, if is dirty

Reimplemented from Ogre::HardwareBufferManagerBase.

◆ createUniformBuffer() [2/2]

HardwareUniformBufferSharedPtr Ogre::GLES2HardwareBufferManager::createUniformBuffer ( size_t  sizeBytes,
HardwareBuffer::Usage  usage,
bool  useShadowBuffer,
size_t  binding,
const String name = "" 
)

Create a uniform buffer.

◆ getGLType()

static GLenum Ogre::GLES2HardwareBufferManager::getGLType ( VertexElementType  type)
static

Utility function to get the correct GL type based on VET's.

◆ getStateCacheManager()
