I have the following code: my object: (I am aware the normals are a little funny, but they render fine with nvidia VAR and normal vertex arrays).

	box_vertex[0] = -1.0f; // x 
	box_vertex[1] = -1.0f; // y
	box_vertex[2] =  1.0f; // z

	box_vertex[3] = -1.0f;
	box_vertex[4] =  1.0f;
	box_vertex[5] =  1.0f;

	box_vertex[6] =  1.0f;
	box_vertex[7] =  1.0f;
	box_vertex[8] =  1.0f;

	box_vertex[9] =   1.0f;
	box_vertex[10] = -1.0f;
	box_vertex[11] =  1.0f;

	box_vertex[12] =  1.0f;
	box_vertex[13] = -1.0f;
	box_vertex[14] = -1.0f;

	box_vertex[15] =  1.0f;
	box_vertex[16] =  1.0f;
	box_vertex[17] = -1.0f;

	box_vertex[18] = -1.0f;
	box_vertex[19] =  1.0f;
	box_vertex[20] = -1.0f;

	box_vertex[21] = -1.0f;
	box_vertex[22] = -1.0f;
	box_vertex[23] = -1.0f;



	box_normal[0] = -0.71f;
	box_normal[1] =     0;
	box_normal[2] =  0.71f;

	box_normal[3] = -0.71f;
	box_normal[4] =     0;
	box_normal[5] =  0.71f;

	box_normal[6] =  0.71f;
	box_normal[7] =     0;
	box_normal[8] =  0.71f;

	box_normal[9] =  0.71f;
	box_normal[10] =    0;
	box_normal[11] = 0.71f;

	box_normal[12] =  0.71f;
	box_normal[13] =     0;
	box_normal[14] = -0.71f;

	box_normal[15] =  0.71f;
	box_normal[16] =     0;
	box_normal[17] = -0.71f;

	box_normal[18] = -0.71f;
	box_normal[19] =     0;
	box_normal[20] = -0.71f;

	box_normal[21] = -0.71f;
	box_normal[22] =     0;
	box_normal[23] = -0.71f;

	box_tex[0] = 0.0f;
	box_tex[1] = 1.0f;

	box_tex[2] = 0.0f;
	box_tex[3] = 0.0f;

	box_tex[4] = 1.0f;
	box_tex[5] = 0.0f;

	box_tex[6] = 1.0f;
	box_tex[7] = 1.0f;

	box_tex[8] = 0.0f;
	box_tex[9] = 1.0f;

	box_tex[10] = 0.0f;
	box_tex[11] = 0.0f;

	box_tex[12] = 1.0f;
	box_tex[13] = 0.0f;

	box_tex[14] = 1.0f;
	box_tex[15] = 1.0f;

	box_indices[0] = 4;
	box_indices[1] = 7;
	box_indices[2] = 3;
	box_indices[3] = 0;
	box_indices[4] = 0;
	box_indices[5] = 1;
	box_indices[6] = 7;
	box_indices[7] = 6;
	box_indices[8] = 4;
	box_indices[9] = 5;
	box_indices[10] = 3;
	box_indices[11] = 2;
	box_indices[12] = 0;
	box_indices[13] = 1;
	box_indices[14] = 1;
	box_indices[15] = 6;
	box_indices[16] = 2;
	box_indices[17] = 5;

 
initializing the object buffers:
	vertexObject = glNewObjectBufferATI(sizeof(box_vertex), box_vertex, GL_STATIC_ATI);
	textureObject = glNewObjectBufferATI(sizeof(box_tex), box_tex, GL_STATIC_ATI);
	normalObject = glNewObjectBufferATI(sizeof(box_normal), box_normal, GL_STATIC_ATI);

 
drawing it:
	glEnableClientState(GL_VERTEX_ARRAY);
	glEnableClientState(GL_TEXTURE_COORD_ARRAY);
	glEnableClientState(GL_NORMAL_ARRAY);

	glBindTexture(GL_TEXTURE_2D, texture[filter]);

		glArrayObjectATI(GL_TEXTURE_COORD_ARRAY, 2, GL_FLOAT, sizeof(box_tex), textureObject, 0);
		glArrayObjectATI(GL_NORMAL_ARRAY, 3, GL_FLOAT, sizeof(box_normal), normalObject, 0);
		glArrayObjectATI(GL_VERTEX_ARRAY, 3, GL_FLOAT, sizeof(box_vertex), vertexObject, 0);

		glDrawElements(GL_TRIANGLE_STRIP, 18, GL_UNSIGNED_INT, box_indices);

	glDisableClientState(GL_NORMAL_ARRAY);
	glDisableClientState(GL_TEXTURE_COORD_ARRAY);
	glDisableClientState(GL_VERTEX_ARRAY);

 
for some reaso I only see 1 texture triangle instead of a texture cube. What am I doing wrong ? Thanks! Nitzan ------------------------- www.geocities.com/nitzanw www.scorchedearth3d.net -------------------------

Ok,
I re-read the various tutorials and changed my code to the following calls, but someone it seems like my vertex info is getting corrupted and random triangles are being drawn:



vertexObject = glNewObjectBufferATI(24*4, box_vertex, GL_STATIC_ATI);
normalObject = glNewObjectBufferATI(24*4, box_normal, GL_STATIC_ATI);
textureObject = glNewObjectBufferATI(16*4, box_tex, GL_STATIC_ATI);

glArrayObjectATI(GL_TEXTURE_COORD_ARRAY, 2, GL_FLOAT, 16, textureObject, 0);
glArrayObjectATI(GL_NORMAL_ARRAY, 3, GL_FLOAT, 24, normalObject, 0);
glArrayObjectATI(GL_VERTEX_ARRAY, 3, GL_FLOAT, 24, vertexObject, 0);

glDrawElements(GL_TRIANGLE_STRIP, 18, GL_UNSIGNED_INT, box_indices);



Does anyone have any ideas ?

Nitzan
