Class Texture2dProgram

KERNEL_SIZE

public static final int KERNEL_SIZE

Constant Value

9

Texture2dProgram( Texture2dProgram.ProgramType programType )

Prepares the program in the current EGL context.

public Texture2dProgram(Texture2dProgram.ProgramType programType)

Constructor Parameters

programType

release()

Releases the program.

The appropriate EGL context must be current (i.e. the one that was used to create the program).

public void release()

getProgramType()

Returns the program type.

public com.android.grafika.gles.Texture2dProgram.ProgramType getProgramType()

createTextureObject()

Creates a texture object suitable for use with this program.

On exit, the texture will be bound.

public int createTextureObject()

setKernel( float[] values, float colorAdj )

Configures the convolution filter values.

public void setKernel(float[] values,float colorAdj)

Method Parameters

values

Normalized filter values; must be KERNEL_SIZE elements.

colorAdj

setTexSize( int width, int height )

Sets the size of the texture. This is used to find adjacent texels when filtering.

public void setTexSize(int width,int height)

Method Parameters

width

height

draw( float[] mvpMatrix, FloatBuffer vertexBuffer, int firstVertex, int vertexCount, int coordsPerVertex, int vertexStride, float[] texMatrix, FloatBuffer texBuffer, int textureId, int texStride )

Issues the draw call. Does the full setup on every call.

public void draw(float[] mvpMatrix,FloatBuffer vertexBuffer,int firstVertex,int vertexCount,int coordsPerVertex,int vertexStride,float[] texMatrix,FloatBuffer texBuffer,int textureId,int texStride)

Method Parameters

mvpMatrix

The 4x4 projection matrix.

vertexBuffer

Buffer with vertex position data.

firstVertex

Index of first vertex to use in vertexBuffer.

vertexCount

Number of vertices in vertexBuffer.

coordsPerVertex

The number of coordinates per vertex (e.g. x,y is 2).

vertexStride

Width, in bytes, of the position data for each vertex (often vertexCount * sizeof(float)).

texMatrix

A 4x4 transformation matrix for texture coords. (Primarily intended for use with SurfaceTexture.)

texBuffer

Buffer with vertex texture data.

textureId

texStride

Width, in bytes, of the texture data for each vertex.
