Just like this picture (taken from Blenders homepage, http://www.blender.org), you can see axes on the bears arm even if they are "inside" the arm
Im rendering in dx11.

[source lang="cpp"] ID3D11DepthStencilState* EnableAllDSS; D3D11_DEPTH_STENCIL_DESC depthdesc; memset(&depthdesc, 0, sizeof(depthdesc)); depthdesc.DepthEnable = (BOOL) false; depthdesc.DepthWriteMask = D3D11_DEPTH_WRITE_MASK_ZERO; depthdesc.DepthFunc = D3D11_COMPARISON_NEVER; depthdesc.StencilEnable = (BOOL) false; HR(device->CreateDepthStencilState(&depthdesc, &EnableAllDSS));[/source]
Then just set EnableAllDDS as the depth stencil state when rendering the axis arrows and reset it when done rendering them.

It appears that the gentleman thought C++ was extremely difficult and he was overjoyed that the machine was absorbing it; he understood that good C++ is difficult but the best C++ is well-nigh unintelligible.

Isn't Ashaman73's solution the only proper one in this thread?

(d3d render state ztest off just at drawins Axis and then turn it on )
It's so easy I see some wrong answer above
but you need self depth test? Am I right?
then you need mask like stencil and so many other way..
How about this?
draw Axis to other texture and compositing it It's very easy and simple
but you must draw 3 times but you can debug Axis and object so easily ..I never use stencil. and I think It's not necessary at all at over DX 9
any other help plz let me know
Ah sorry you just need turn on off Z test that's all I confuse with others message
sorry I'm new here and I'm Korean
