Detailed Description

Manage Texture loading and registration.

TextureManager allows to store texture globally such that different object can share textures based on their handle or name. Name uniqueness is not guaranteed by the manager, take care in case of search texture by name.

Member Function Documentation

addTexture()

TextureManager::TextureHandle Ra::Engine::Data::TextureManager::addTexture

(

const TextureParameters &

p

)

Add a texture given its TextureParameters.

Returns

a TextureHandle that uniquely identify the texture in the manager.

Definition at line 21 of file TextureManager.cpp.

Here is the call graph for this function:

deleteTexture()

void Ra::Engine::Data::TextureManager::deleteTexture

(

const TextureHandle &

handle

)

Remove a managed texture identified by handle.

Texture dtor will register the delete texture gpu task.

Definition at line 104 of file TextureManager.cpp.

getTexture() [1/2]

Texture * Ra::Engine::Data::TextureManager::getTexture ( const std::string & name )

inline

Convinience function to obtain Texture ptr from name.

Definition at line 46 of file TextureManager.hpp.

getTexture() [2/2]

Texture * Ra::Engine::Data::TextureManager::getTexture

(

const TextureHandle &

handle

)

Get raw texture ptr from handle.

The texture is still managed by the manager. Do not delete the return ptr.

Definition at line 91 of file TextureManager.cpp.

getTextureHandle()

TextureManager::TextureHandle Ra::Engine::Data::TextureManager::getTextureHandle

(

const std::string &

name

)

Get a texture handle from textue name.

It search for the first texture in the set of managed texture that have this name.

Returns

An handle to the texture or InvalidIndex if no texture with this name is found

Definition at line 95 of file TextureManager.cpp.

Here is the call graph for this function:

loadTextureImage()

ImageParameters Ra::Engine::Data::TextureManager::loadTextureImage ( const std::string & filename, bool linearize = false )

static

Load filename and fill ImageParameters according to filename content.

Note

only loads 2D image file for now.

Parameters

filename

fully qualified image filename. See stbi_load_image for supported file format.

Returns

ImageParameters corresponding to filename content, image.parameters.texels contains actual image data. In case of loading error, texels is nullptr, width = height = 0.
