How do I use native APIs to calculate MD5? How do I use RSA to verify a signature? How do I encrypt a large file using SM4? How do I use the RSA public key (pk) to encrypt a piece of text? What should I do if AES decryption fails? How do I use the AES algorithm to...
So far I've managed to calculate approximate surface normals at the line coordinates and the lines are now lit variably in space, but not in the same manner as the surface lighting it should match: % The 2D elevation map of `peaks` projected onto a ...
I have a table with sales data, and I want to calculate the total sales for each product category. Can you help me with the M query for that?ChatGPT: Of course! To calculate the total sales for each product category, you can use the Group By transformation in Power BI’s Power ...
Hi everybody, I will try to be as clear as possible. I generate an image from a STL file (so a 3D image). Then I calculate the unit normal vectors on the entire surface and then I plot on the same image their y-coordinate, in order to have a clear visualization of how the defor...
I mean to get the existing vertex tangent, not to recalculate it. I found some articles, but they calculate the tangent based on the UVs of the three vertices of a triangle. However, this may have some problems,the normals calculated based on individual faces may not necessarily match th...

Here you see the four major vectors you'll need to calculate the diffuse and specular colors contributed by each light. The light direction vector is the light blue arrow pointing to the light. The normal vector is the green arrow standing straight up. The reflection vector is the dark blue...
(for which we need to calculate a shadowmap every frame frame), the number of drawcalls underShadowFrustumQueriesis 3. I suspect this is because one of the lights’ bounding volume intersects the camera’s near plane so Unreal assumes that it will be visible anyway. Also, worth mentioning ...
