Rendered objects are all black.

[peterstroeiman]

Hi.

I have managed to render some objects on the screen. My vertices contain no color information, only coordinates

Code: Select all

struct Vertex
{
	float x,y,z;
};

To set the colod I call

Code: Select all

sceGuColor( 0xffffff00 );

Then render the objects using

Code: Select all

sceGuDrawArray(
GU_TRIANGLES,GU_VERTEX_32BITF|GU_TRANSFORM_3D,
	vertexCount,0, vertexData );

But the rendered objects are all black.

What am I doing wrong?

you have to use that structure:

struct Vertex
{
float u,v;
UINT color;
float x,y,z;
};

but..

I shouldn't put texture coordinates and color info in the struct if I don't specify a texture format and color format in the call to sceGuDrawArray.

And besides, my geometry seems correct, which means that the function sees the vertex format I specified.

ok i read the h file again, i guess you can use any structure as long as it's aligned to 32bit which is the case for you

if you have lighting enabled you need to specify normals for your objects.

I found out the problem.

I had texture mapping enabled, which I shouldn't when not using it.
