问题 I have spent the last week developing an upload system where my application could take a camera RAW file, draw out the metadata and then save the file as a jpg. I use ExifTool to draw out the metadata. I use ImageMagick to convert the file to .jpg. I am working with 4 file types to begin with CRW, RAF, ARW and NEF. However, the uploading of different RAW files in the browser results in the different file types being identified in the upload. This was a problem for 2 of the different RAW types

问题 I'm trying to make a FPS camera in WebGL. When I move the camera from the initial position and then rotate, the camera moves along the start position instead of the new position. The translation and rotation are made with glMatrix.js library. I have the variables: var rotateY = 0; // For rotating along the Y axis var fronBackMovement = 0; // Front and back movement var sideMovement = 0; // Movement from side to side Keyboard events: // Movement if( key.w == true ){ fronBackMovement += 5; } if

问题 Game: In a simple 2D Portrait Game made in Unity, I have a GameObject (Player) that has a fixed location and which is moving upwards. The Camera follows the Player and animated Obstacles are spawning from time to time moving left to right. The attached Screenshot shows the Scene. The Problem: The Movement is not smooth, as it seems like the Player is jittering. I think I already identified one of the causes: Big variation of Time.deltaTime. Average value is 0.0167, but I had variations.
