Detailed Description

A GPU mesh utility class that works with G3D::UniversalSurface.

A set of lines, points, quads, or triangles that have a single UniversalMaterial and can be rendered as a single OpenGL primitive using RenderDevice::sendIndices inside a RenderDevice::beginIndexedPrimitives() block.

allocateBoneTexture()

static shared_ptr<Texture> G3D::UniversalSurface::GPUGeom::allocateBoneTexture ( int  width, int  height  )

static

Bone textures are reused between frames to minimize allocation costs.

create() [1/2]

static shared_ptr<GPUGeom> G3D::UniversalSurface::GPUGeom::create ( const shared_ptr< GPUGeom > &  other )

create() [2/2]

createShared()

template<class T , class ... ArgTypes>

static shared_ptr<T> G3D::ReferenceCountedObject::createShared ( ArgTypes &&...  args )

inlinestaticprotectedinherited

Like std::make_shared, but works for protected constructors.

Call as createShared<myclass>.

hasBones()

bool G3D::UniversalSurface::GPUGeom::hasBones ( ) const

inline

hasGeometry()

bool G3D::UniversalSurface::GPUGeom::hasGeometry ( ) const

inline

True if this part has some geometry.

operator delete()

static void G3D::UniversalSurface::GPUGeom::operator delete ( void *  p )

inlinestatic

operator new()

static void* G3D::UniversalSurface::GPUGeom::operator new ( size_t  size )

setShaderArgs()

void G3D::UniversalSurface::GPUGeom::setShaderArgs

(

Args &

args

)

const

Sets.

Parameters

args	index array, and the following vertex attributes: vec4 g3d_Vertex; vec3 g3d_Normal; [vec2 g3d_TexCoord0;] [vec2 g3d_TexCoord1;] [vec4 g3d_PackedTangent;] [vec4 g3d_VertexColor;] [ivec4 g3d_BoneIndices;] [vec4 g3d_BoneWeights;]

and uniform: [sampler2D boneMatrixTexture]

and macros: [HAS_BONES]

where square brackets denotes optional attributes, dependent on whether the geom contains valid values for them.

This binds attribute arrays, so it cannot accept a UniformTable argument.
