Hi,I would like to understand how works the decomposition tile_equalizer, so I am trying to build a simple application using tile_equilizer in the config file which should render a picture where each tile has a different color. Something like a chess table but with many colours.
I am using the attached config file and my code for Channel::frameDraw( const eq::uint128_t& frameID ) is:
{
EQ_GL_CALL( glEnable(GL_SCISSOR_TEST));
EQ_GL_CALL( eq::Channel::applyBuffer() );
EQ_GL_CALL( eq::Channel::applyViewport() );
eq::PixelViewport viewport = getPixelViewport();
// Choose the tile colour r g b
float * data = new float [3*viewport.h*viewport.w];
for(int i=0; i<3*viewport.w*viewport.h; i+=3)
{
data[i] = r;
data[i+1] = g;
data[i+2] = b;
}
EQ_GL_CALL( glDrawPixels(viewport.w, viewport.h, GL_RGB,
GL_FLOAT, data) );
delete[] data;
}
This code render just the first tile in the position (0,0) but not the
others.
I need any thing else to render my multi colour chess table. I really appreciate any help you can provide. Cheers -- Carlos Duelo
