qml porting changes the opengl scene placement

[sajis997]

Hello forum,

I had a simple opengl triangle application . Check the screen-shot:

When I port the same application to qml following the documentation - "Scene Graph - OpenGL Under QML", I do get the triangle as an underlay, but the placement of the triangle changed as follows:

The basic OpenGL is exactly same as the original one . Thecode sippet that shapes the triangle is as follows:

//setup triangle geometry
	//setup triangle vertices
	vertices[0].color=glm::vec3(1,0,0);
	vertices[1].color=glm::vec3(0,1,0);
	vertices[2].color=glm::vec3(0,0,1);
 
	vertices[0].position=glm::vec3(-1,-1,0);
	vertices[1].position=glm::vec3(0,1,0);
	vertices[2].position=glm::vec3(1,-1,0);
 
	//setup triangle indices
	indices[0] = 0;
	indices[1] = 1;
	indices[2] = 2;

//setup triangle geometry
	//setup triangle vertices
	vertices[0].color=glm::vec3(1,0,0);
	vertices[1].color=glm::vec3(0,1,0);
	vertices[2].color=glm::vec3(0,0,1);

	vertices[0].position=glm::vec3(-1,-1,0);
	vertices[1].position=glm::vec3(0,1,0);
	vertices[2].position=glm::vec3(1,-1,0);

	//setup triangle indices
	indices[0] = 0;
	indices[1] = 1;
	indices[2] = 2;

I am getting different placement of the triangle with qml where opengl is underlay.

Any thoughts?


Thanks
