Function documentation

U4DEngine::U4DRenderMultiImage::U4DRenderMultiImage(U4DImage* uU4DImage)

Constructor for class.

Parameters
uU4DImage	image entity

It sets the image entity it will manage

U4DEngine::U4DRenderMultiImage::~U4DRenderMultiImage()

Destructor for class.

sets the multi-image buffer to null

void U4DEngine::U4DRenderMultiImage::loadMTLTexture() virtual

Loads image texture into GPU.

It decodes the current texture image, creates a texture object, a texture sampler, and loads the raw data into a buffer

void U4DEngine::U4DRenderMultiImage::render(id<MTLRenderCommandEncoder> uRenderEncoder) virtual

Renders the current entity.

Parameters
uRenderEncoder	Metal encoder object for the current entity

Updates the space matrix and any rendering flags. It encodes the pipeline, buffers and issues the draw command

void U4DEngine::U4DRenderMultiImage::setTexture0(const char* uTexture) virtual

Sets the texture image for the image.

Parameters
uTexture	texture name

It sets the texture that will be decoded into raw data and loaded into the texture buffer

void U4DEngine::U4DRenderMultiImage::setTexture1(const char* uTexture) virtual

Sets the texture1 image for the image.

Parameters
uTexture	texture1 name

It sets the texture that will be decoded into raw data and loaded into the texture buffer

void U4DEngine::U4DRenderMultiImage::createSecondaryTextureObject()

Create secondaray texture for multiple images.

The main image uses the diffuse texture. The secondary image uses the ambient texture

void U4DEngine::U4DRenderMultiImage::loadMTLAdditionalInformation() virtual

Loads the additional information.

loads the secondary texture into the buffer

void U4DEngine::U4DRenderMultiImage::updateMultiImage()

Updates the image to render

Changes the image of the entity to render
