As a good young man of the 21st century, Xu Yun didn't have a habit of eavesdropping on others.
But considering the special situation of this dungeon, after some hesitation, he still quietly sneaked to the side of the tent.
At this time, the bottom of the tent faintly showed some bright light, and some rustling sounds came from inside the tent.
"Will, do you like it on top or at the bottom?"
"At the bottom."
"Okay, can you keep up with this speed? I'm speeding up....."
"Mr. Thomson, easier....."
Xu Yun: "????"
No way?
Really just know the man up?
Just as he was about to quietly leave the tent, Thomson suddenly said:
"In the Cartesian coordinate system, if you choose this tangent line at the bottom, then the vertex normal will change."
"As a result...see? Their direction in three-dimensional space is very likely not perpendicular..."
"And if the tangent space is defined at each vertex, then two more steps are needed to get the normalized TBN matrix..."
