BufferSpec

Stay organized with collections Save and categorize content based on your preferences.

Specification of a pixel buffer. A pixel buffer can have color, depth and stencil attachments and mostly corresponds to the OpenGL concept of a framebuffer object. However, since there can be multiple such objects for each frame, we avoid calling them "framebuffers". Pixel buffers which are part of the currently acquired frame are immutable, i.e., they cannot be resized or otherwise reconfigured.

Nested Classes Public Methods int getSamples

()

Gets the number of samples per pixel in the buffer to be created.

void getSize

(

Point

bufferSizeOut)

Gets the size of the buffer to be created.

static boolean static boolean void setColorFormat

(int format)

Sets the format of the color attachment for the buffer to be created.

void setDepthStencilFormat

(int format)

Sets the format of the packed depth-stencil attachment for the buffer to be created.

void setMultiviewLayers

(int numLayers)

Sets the number of layers in a framebuffer backed by an array texture.

void setSamples

(int samples)

Sets the number of samples per pixel in the buffer to be created.

void setSize

bufferSize)

Sets the size of the buffer to be created.

void shutdown

()

Shuts down the BufferSpec instance, freeing associated resources.

Public Methods public int getSamples ()

Gets the number of samples per pixel in the buffer to be created.

Returns

Value >= 1 giving the number of samples. 1 means multisampling is disabled. Negative values and 0 are never returned.

public void getSize (Point bufferSizeOut)

Gets the size of the buffer to be created.

Parameters bufferSizeOut The (output) size of the pixel buffer. The default is equal to the recommended render target size at the time when the specification was created. public static boolean isValidColorFormat (int format)

Checks if the given integer is a legal color format.

public static boolean isValidDepthStencilFormat (int format)

Checks if the given integer is a legal depth-stencil format.

public void setColorFormat (int format)

Sets the format of the color attachment for the buffer to be created.

public void setDepthStencilFormat (int format)

Sets the format of the packed depth-stencil attachment for the buffer to be created.

public void setMultiviewLayers (int numLayers)

Sets the number of layers in a framebuffer backed by an array texture. Default is 1, which means a non-layered texture will be created. Not all platforms support multiple layers, so clients can call GvrApi.isFeatureSupported(GvrApi.Feature.MULTIVIEW) to check.

Parameters numLayers The number of layers in the array texture. public void setSamples (int samples)

Sets the number of samples per pixel in the buffer to be created.

Parameters samples The number of samples. Negative values are an error. The values 0 and 1 are treated identically and indicate that multisampling should be disabled. public void setSize (Point bufferSize)

Sets the size of the buffer to be created.

Parameters bufferSize The size. Width and height must both be greater than zero. Otherwise, the application is aborted. public void shutdown ()

Shuts down the BufferSpec instance, freeing associated resources.

Note: The caller is responsible for ensuring that this BufferSpec isn't used after shutdown.
