How to get object in WebGL 3d space from a mouse click coordinate

由 断了今生、忘了曾经 提交于 2020-02-09 01:10:56
问题 I'm building a boardgame in WebGL. The board can be rotated/zoomed. I need a way to translate a click on the canvas element (x,y) into the relevant point in 3D space (x, y, z). The ultimate result is that I want to know the (x, y, z) coordinate that contains the point that touches the object closest to the user. For instance, the user clicks a piece, and you imagine a ray traveling through 3D space that goes through both the piece and the game board, but I want the (x, y, z) coord of the

Get 3d Coordinate Of Mouse In Axis

问题 I used below code from link to plot mouse position in axes(when mouse moving in axes) : point = get(gca, 'CurrentPoint'); % mouse click position camPos = get(gca, 'CameraPosition'); % camera position camTgt = get(gca, 'CameraTarget'); % where the camera is pointing to camDir = camPos - camTgt; % camera direction camUpVect = get(gca, 'CameraUpVector'); % camera 'up' vector zAxis = camDir/norm(camDir); upAxis = camUpVect/norm(camUpVect); xAxis = cross(upAxis, zAxis); yAxis = cross(zAxis, xAxis)

How can my view respond to a mousewheel?

问题 I have a view with an onTouch that can distinguish between touch input and left/middle/right mouse clicks, as in @Override public boolean onTouch(View v, MotionEvent event) { if (event.getButtonState() == MotionEvent.BUTTON_PRIMARY) // API 14 required ... ... } I'd also like this view to respond to the mousewheel. onTouch is not the way, nor have I found any other event handler to respond to the mousewheel. Maybe the view can pretend to be scrollable and do its own thing with scrolling

Pass mouse events to applications behind from a Java UI

由 笑着哭i 提交于 2020-01-29 05:37:07
问题 The question I have is exactly same in requirement as How to pass mouse events to applications behind mine in C#/Vista? , but I need the same for a Transparent Java UI. I can easily create a transparent Java UI using 6.0 but couldn't get any info about passing events through the app to any applications(say a browser) behind. 回答1: I believe this will answer your question. To run it you will need Java 6 update 10 and above. I tested it on Windows Vista import java.awt.AlphaComposite; import

Mouse position with screen scrolling in SFML

问题 Im trying to create a block placement with snap to grid. Everything is working, and in my head this should update the position of the mouse relative to the window each frame right? sf::Vector2i position = sf::Mouse::getPosition(window.mywindow); //get position int xSnap = (position.x / gridWidth) * gridWidth; int ySnap = (position.y / gridHeight) * gridHeight; But i also have screen scrolling using if (player.playerSprite.getPosition().x + 16 > screenDimensions.x / 2) position.x = player

How to calculate look at point to move the camera with the mouse in OpenGL/GLUT?

问题 This will be confusing for me to explain so please bear with me. I've already implemented most type of movements and rotations in my camera class, everything is working with the keyboard, now I want to implement the mouse. I capture the mouse movement like this: #define SENSITIVITY 25.0f void main(void) { (...) glutPassiveMotionFunc(processPassiveMotion); glutWarpPointer(WINDOW_WIDTH / 2, WINDOW_HEIGHT / 2); glutSetCursor(GLUT_CURSOR_NONE); (...) } void processPassiveMotion(int x, int y) {
