can you help me .how to load mesh by myself formate in d3d? I can read file but I dont know how to render it ,I render it all ways wrong.thanks!!

Hi

Can we see what you have so far? It will be easier to help you if we know what steps you have taken.

this is my file header and this is the file information!can you help me how to read it and how to render it in d3d!thanks

please edit your post, then we will have a look. Thanks.
