bị bug với vertex buffer

[ngocquang19877]

tôi có tạo 1 class vertex buffer.nhưng tôi không thể nào render nó lên màn hình được,nếu ai có khả năng xin debug dùm tôi cám ơn nhiều.

ở dòng dứoi là dòng tôi init shape cho cái class này.tôi viết code cũng dễ hiểu.mong mọi người chỉ dùm

anh here the code i init shape for class vertex

quang[0].position=D3DXVECTOR3(150.0f, 50.0f, 0.5f);
quang[0].color=RGB(255,0,0);
quang[0].tu=0.0f;
quang[0].tv=1.0f;

quang[1].position=D3DXVECTOR3(250.0f, 250.0f, 0.5f);
quang[1].color=RGB(255,0,0);
quang[1].tu=1.0f;
quang[1].tv=0.0f;

quang[2].position=D3DXVECTOR3(50.0f, 250.0f, 0.5f);
quang[2].color=RGB(255,0,0);
quang[2].tu=0.0f;
quang[2].tv=1.0f;

quang[3].position=D3DXVECTOR3(131.0f,2.0f,3.0f);
quang[3].color=RGB(255,0,0);
quang[3].tu=1.0f;
quang[3].tv=0.0f;
