Apply texture to specific "square" (two triangles) of Mesh Plane unity

I am looking for a way to apply a texture to a specific square of a mesh when that square is clicked on. I know how to get the vertices of the square from a Physics.raycast & converting the triangle vertices. My problem is I don't know how to apply…

UV Mapping a cube in Three.js not joining faces correctly

I have successfully applied an image texture to a cube via UV mapping (to produce a photo-sphere viewer). Although the texture is perfectly aligned with cube faces, the lines at which faces join are visible as thin straight lines. The same problem…

Determine fourth set of UV coordinates from the first three

Say that I have a quad, and I am applying a pool table texture to it. I know the UV coordinates for the first three vertices (highlighted in blue) but not the fourth. For example in the image above, I know that the top left coordinates are [0, 0],…

Texturing bug in Jmonkey

To my immense surprise, it seems impossible to find any other people having this problem -- I can use Jmonkey to import a mesh (in my case a gear), but it doesn't properly map the texture (which is supposed to look like wood), only texturing a few…

Smoothly mapping a 2D uv point onto a 3D xyz sphere

I have been trying to procedurally generate a sphere's surface using simplex noise, and I figured that in order to get smooth, non-distorted noise I need to map each uv pixel to an xyz coordinate. I have tried a few different algorithms, with the…

How to calculate UVs of a flat poligon mesh

My game generates a flat surface (the floor of a building). It's a flat poligon mesh as shown in the picture: The poligon is generated procedurally and will be different each time. I need to map UV coordinates so that a standard square texture of,…

Number of points in UV sphere

I'm trying to generate a mesh from a sphere of radius r. My goal is to create a UV sphere such that every point on the polyhedron has distance from the sphere smaller than tol. The following code creates a grid of points on the sphere. How can I…

UV mapping a proceduraly generated sphere in OpenGL

I'm trying to UV a 2D texture on a globe. Here's a piece of code: double delta = 0.0, // angle of latitude theta = 0.0, // angle of longitude theta_interval = (2.0 * M_PI) / latitude, // angle of latitude delta_interval = M_PI /…

UV unwrap on Runtime optimization

I'm trying to create UVs @ runtime, I'm using a BOX type UVs (similar to BOX UVW in 3ds max) and based my calculation on the face orientation. I know it's not a good option to create it a runtime but I have no choice :( it's saved after…

How are UV coordinates measured?

I've got a 3D modeling program exporting a UV mapped 3D model. However the UV coordinates seem to be invalid or using a system I don't understand. I need help in understanding how UV coordinates map to the pixels of the bitmap (X, Y) I've got a…

Texture UV coords not lining up as expected in Unity3D

I'm creating a mesh programmatically in Unity3D. Each section of the mesh is setup with 4 verts: // 1 ----- 2 // | a / | // | / b | // 3 ----- 4 My UVs are: 1 = 0, 1 2 = 0.125, 1 3 = 0, 0.875 4 = 0.125, 0.875 My texture is 2048x2048. The tile…
