Method Detail

deleteObj

protected void deleteObj()

Specified by:

deleteObj in class GL.JavaObject

get

public int get(int ind)

Get a value from this byte vector.

Parameters:

ind - The index of the value to get.

readFromBuffer

public void readFromBuffer(GL.RenderingSurface win,
                           java.lang.String buffer,
                           int x,
                           int y,
                           int width,
                           int height,
                           java.lang.String format,
                           java.lang.String type)

Read pixels from an OpenGL buffer into this bytevector.

Parameters:

win - The window to read from

buffer - The OpenGL buffer to read from, e.g. "FRONT", "BACK"

x - The x coordinate to read from

y - The y coordinate to read from - note that this uses OpenGL's default coordinate system which is the opposite of ours in the y direction.

format - The format which to store in the vector, e.g. "RGB", "RGBA"

type - The type to read to, e.g. "FLOAT" or "UNSIGNED_BYTE"

drawPixels

public void drawPixels(GL.Window win,
                       int x,
                       int y,
                       float z,
                       int width,
                       int height,
                       java.lang.String format,
                       java.lang.String type)

get

public byte[] get()

Get the values from the vector as an array of bytes. Not sure if this is good since bytes are signed in Java. XXX Same for shorts?

getInts

public int[] getInts()

Get the values from the vector as an array of ints. Each integer is formed by packing 4 bytes.

shade

public int shade(int w,
                 int h,
                 int d,
                 int comps,
                 java.lang.String shaderName,
                 java.lang.String[] params)

Shade the given Texture into this bytevector, using 32-bit floats. Sets the bytevector length to w*h*(d > 0?d : 1) * comps * 4
