### Explain the difference between extrapolation and interpolation

http://www.unagames.com/blog/daniele/2010/06/fixed-time-step-implementation-box2d here there are two algorithms of smoothing in case of fixed time step physics simulation. I don't understand the ...

### How to smooth mask texture edges correctly regardless it's size

I have a texture intended as a mask. The texture type is GL_R32F (32 bit float) and the data inside is a signed distance field (= value of each texel is distance to nearest mask edge). For test ...

### LibGDX: Smooth movement on a grid based game

I'm making a game with LibGDX where the player is on a grid (like a Chess board). For now, I'm moving the player by teleporting him 16px in a direction. I'd like to use the delta time to make smooth ...

### How to smooth the model/texture look from a distance?

(First of all, I really didn't know how to title my question so it tells exactly what I mean so if anyone has a better title feel free to edit my question or leave a comment.) Look at the water in ...

### OpenGL - How can I make the edges of this textured circle smoother?

I'm building a game and I've applied a certain texture (RAW file) to a circle (GL_POLYGON) in OpenGL. It loads correctly, with the right size and all, but the edges seem a bit jagged and I would ...

### Cubic bezier for easing?

I would like to find out what Y is if X is a certain number from a cubic bezier curve to make a custom easing function, like it's done on this site: http://cubic-bezier.com/ Does anyone know a formula ...

### OpenGL - How to draw a transition of two textures on one quad?

I know when drawing a rectangle, if we select red and draw two vertices, and then select yellow and draw the other two vertices, the entire rectangle will show a nice transition of color between those ...

### Find out which way to rotate based on current rotation and final rotation [duplicate]

I have one object that I want to rotate to a certain angle with 'smooth' rotation. I looked up on how to solve that and I came up with this: enter image description here But how do I know in what ...

### Improving the performance of smooth movement up and down

I would like to achieve a smooth movement of a game object up and down. The way I have always seen this done is via a sine wave, and adding the value of y for a specified X to the game objects value ...

### Why do I have to run my 2D game at 300+ FPS for movement to be passably smooth?

I'm working on a simple game with SFML, and the only way to make the game reasonably smooth is to allow it the highest framerate my machine can handle (that is, giving it no limit). 60 FPS in my game ...

### Algorithm for smoothing a network object's movement

We are building multiplayer game where there's no central server managing the game. Each player is responsible for sending out its state to all connected players. In addition, all clients run ...

### Smooth animation when using fixed time step

I'm trying to implement the game loop where the physics is independent from rendering but my animation isn't as smooth as I would like it to be and it seems to periodically jump. Here is my code: // ...

### Smoothing the scrolling path in 2D

I have the following problem: In a 2D game the screen can scroll in any of the 4 directions. Basically, the center of the screen during scrolling moves from (x1,y1) to (x2, y2) whereby (x1,y1) is the ...

### Particle trajectory smoothing: where to do the simulation?

I have a particle system in which I have particles that are moving to a target and the new targets are received via network. The list of new target are some noisy coordinates of a moving target stored ...

### smooth shading vs flat shading, what's the difference in the models?

I'm loading the exact same model with Assimp, except one is exported from Blender, shaded smoothly, and the other was exported from Blender, shaded flatly. Here is my results from loading both into my ...

### Smoothing Heightmap Data

I've made a Heightmap Generator that creates island heightmaps like in this picture: I am dividing the grayscale ( 0 - 255 ) into 4 diferent parts ( water, sand, gras and forrest ) and after ...

### How to achieve smooth movement with a fixed timestep

Previously in the update method of my game I was using a variable time step which provided very smooth movement of a player sprite except when the frame rate would drop, even slightly. At that point I ...

### Where and how to smooth a voxel-based terrain surface?

I want to smooth the blocky terrain in a Minecraft-like world. The smoothing affects visual appearance and physics but not the logic of placing and picking blocks. I have my mathematical formula to ...

### Smooth rotation [duplicate]

I would like to rotate my Player very smooth. At the moment the player stops rotating when I release the button. Also the rotation should get faster, if the player rotates longer. I use XNA and have ...
