[gl4java-usergroup] How to implement translucency through png file which has the alpha parameter?

[Jason G. <go...@re...>]

Hi all,

How do I implement translucency through png file which has the alpha =
parameter?=20

The following is a snippet from my coding but it does not seem to work =
:(

................................................

mapfile_texLoader[index] =3D new PngTextureLoader(gl, glu);

mapfile_texLoader[index].readTexture(getCodeBase(), =
getParameter("mapfile"+index+"_texture"));

if(mapfile_texLoader[index].isOk())

{

gl.glBindTexture(GL_TEXTURE_2D, mapfile_texture[index]);

gl.glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

gl.glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, =
GL_LINEAR_MIPMAP_NEAREST);

.........................................................................=
.........................................

gl.glEnable(GL_BLEND);

gl.glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

// gl.glAlphaFunc(GL_GREATER, 0.1f);

glu.gluBuild2DMipmaps(GL_TEXTURE_2D,

3,

mapfile_texLoader[index].getImageWidth(),

mapfile_texLoader[index].getImageHeight(),

GL_RGBA,

GL_UNSIGNED_BYTE,

mapfile_texLoader[index].getTexture());

................................................



Any ideas?
