Hi I started to study directx12. I don't have any knowledge on prior versions.
I am following this example program HelloWorldTriangle which
rendering a triangle. I want to draw a rectangle so,
I changed
Vertex triangleVertices[] =
{
{ { 0.0f, 0.25f * m_aspectRatio, 0.0f }, { 1.0f, 0.0f, 0.0f, 1.0f } },
{ { 0.25f, -0.25f * m_aspectRatio, 0.0f }, { 0.0f, 1.0f, 0.0f, 1.0f } },
{ { -0.25f, -0.25f * m_aspectRatio, 0.0f }, { 0.0f, 0.0f, 1.0f, 1.0f } }
};
m_commandList->DrawInstanced(3, 1, 0, 0);
to
Vertex triangleVertices[] =
{
{ { 0.0f, 0.25f * m_aspectRatio, 0.0f }, { 1.0f, 0.0f, 0.0f, 1.0f } },
{ { 0.25f, -0.25f * m_aspectRatio, 0.0f }, { 0.0f, 1.0f, 0.0f, 1.0f } },
{ { -0.25f, -0.3f * m_aspectRatio, 0.0f }, { 0.0f, 0.0f, 1.0f, 1.0f } },
{ { -0.25f, -0.2f * m_aspectRatio, 0.0f }, { 0.0f, 0.0f, 1.0f, 1.0f } },
};
m_commandList->DrawInstanced(4, 1, 0, 0);
But still draws a triangle with different angle .. Please explain what I have to change to get a rectangle.
It will be really helpful for me if you give some links or books to headstart directx12 ..
Thanks in advance ..
