The Internet has many places to ask questions about anything imaginable and find past answers on almost everything.

## What is a mesh collider?

The Mesh Collider takes a Mesh Asset and builds its Collider based on that Mesh. It is far more accurate for collision detection than using primitives for complicated Meshes. Mesh Colliders that are marked as Convex can collide with other Mesh Colliders.

## What is convex mesh collider?

Convex mesh collider reduce the mesh to 255 triangles so yes is optimize your mesh of it has more triangles than 255 in it. If your Rigid body is non kinematic and you want to make it collide with other convex and non convex meshes then you have to use convex mesh collider.

## What is a collider in unity?

Collider components define the shape of an object for the purposes of physical collisions. A collider, which is invisible, need not be the exact same shape as the object’s mesh and in fact, a rough approximation is often more efficient and indistinguishable in gameplay.

## What is a mesh in unity?

The shape of a 3D object is defined by its mesh. A mesh is like a net of points, or vertices. … In Unity, there are two primary rendering components: The Mesh Filter, which stores the mesh data of a model, and the Mesh Renderer, which combines the mesh data with materials to render the object in the scene.

## What is a MeSH?

A mesh is a collection of vertices, edges, and faces that describe the shape of a 3D object: … (The plural of vertex is “vertices”) An edge is a straight line segment connecting two vertices. A face is a flat surface enclosed by edges.

## What is a mesh normal?

Abstract. Normal meshes are new fundamental surface descriptions inspired by differential geometry. A normal mesh is a multiresolution mesh where each level can be written as a normal offset from a coarser version. Hence the mesh can be stored with a single float per ver- tex.

## What is mesh UV?

Mesh. uv is an array of Vector2s that can have values between (0,0) and (1,1). The values represent fractional offsets into a texture. … The practical uses is to be able to map arbitrary portions of the texture to specific triangles. For example, they allow you to create a cube in which each side is a different texture.

## What is a mesh renderer?

The Mesh Renderer takes the geometry from the Mesh Filter and renders it at the position defined by the object’s Transform component. The Mesh Renderer GameObject Component as displayed in the Inspector window.

## How do you calculate normals?

A surface normal for a triangle can be calculated by taking the vector cross product of two edges of that triangle. The order of the vertices used in the calculation will affect the direction of the normal (in or out of the face w.r.t. winding).

## What is a normal in graphics?

A normal is the technical term used in Computer Graphics (and Geometry) to describe the orientation of a surface of a geometric object at a point on that surface. … Normals can be thought of as vectors with one caveat: they do not transform the same way that vectors do.

## What is the normal of a plane?

For example, in two dimensions, the normal line to a curve at a given point is the line perpendicular to the tangent line to the curve at the point. … In three dimensions, a surface normal, or simply normal, to a surface at point P is a vector perpendicular to the tangent plane of the surface at P.

## What is the normal of a triangle?

The normal of the triangle, or vector C is the cross product of A and B. … The result is also equal to (0,0,1) as with the right-hand coordinate system example (the vertices coordinates are the same, therefore the vectors A and B are the same as well as the result of the cross product AxB).

## What are triangles with all sides the same length called?

A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.

## What is a normal vector of a plane?

The normal vector, often simply called the “normal,” to a surface is a vector which is perpendicular to the surface at a given point. When normals are considered on closed surfaces, the inward-pointing normal (pointing towards the interior of the surface) and outward-pointing normal are usually distinguished.

## How do you find the normal to a plane?

The normal to the plane is given by the cross product n=(r−b)×(s−b).

## What is the Cartesian equation of a plane?

The Cartesian equation of a plane is , where is the vector normal to the plane. Three points (A,B,C) can define two distinct vectors AB and AC. Since the two vectors lie on the plane, their cross product can be used as a normal to the plane. Substitute one point into the Cartesian equation to solve for d.

## How do you know if two planes are parallel?

To say whether the planes are parallel, we’ll set up our ratio inequality using the direction numbers from their normal vectors. Since the ratios are not equal, the planes are not parallel. To say whether the planes are perpendicular, we’ll take the dot product of their normal vectors.

## What is the line of intersection of two planes?

Two intersecting planes always form a line If two planes intersect each other, the intersection will always be a line. where r 0 r_0 r0​ is a point on the line and v is the vector result of the cross product of the normal vectors of the two planes.

## What is the intersection of two lines called?

Intersecting lines The point where the lines intersect is called the point of intersection. If the angles produced are all right angles, the lines are called perpendicular lines. If two lines never intersect, they are called parallel lines.

## Can 2 planes intersect at a point?

The intersection of two planes is a line. … They cannot intersect at only one point because planes are infinite.

## Does a line go on forever?

The difference between a line and a line segment is that the line segment has two endpoints and a line goes on forever. A line segment is denoted by its two endpoints, as in . A ray has one endpoint and goes on forever in one direction.

## Why must there be 2 lines on a plane?

there must be at least two lines on any plane because a plane is defined by 3 non-collinear points. … Since a plane is defined by 3 non-collinear points, we could have: a line and a point not on that line; two intersecting lines; two parallel lines; or simply 3 non-collinear points.

## Can a solid exist in a plane?

In geometry a solid may exist in a plane. This is false. A plane is defined as a flat and two dimensional surface that extends up to infinitely. The correct statement is – In geometry, a solid may exist in three-dimensional space.

## Is a circle a plane shape?

A circle is a plane closed figure enclosed by a curve, having no sides and no corner (vertex). Every point in the curve is situated at equal distance from a definite point within the closed figure.

## Can triangles have curved sides?

A “side” should be defined as a straight line, or a segment that falls between 2 corners. Any curved side of a shape represents an infinite number of sides, so it would not be a triangle, but in fact an infinity-gon.

## Can a triangle be a plane?

A triangle is made up of three non co-linear points (points that are not on the same line). Because a triangle is made up of three non co-linear points, a triangle can be classified as a plane itself.

## Is Ellipse a plane shape?

An ellipse is a shape that looks like an oval or a flattened circle. In geometry, an ellipse is a plane curve which results from the intersection of a cone by a plane in a way that produces a closed curve. Circles are special cases of ellipses, obtained when the cutting plane is perpendicular to the cone’s axis.
