问题 I am trying to create an earth with three js like this example which is an upgrade from this one. The problem i have is that even thought in the code i add to the scene first the sky , after the earth and at the end the atmosphere the render seams not to understand this order a respondes with this Now when i zoom in and get near the earth object the render is working correct giving this responce.

问题 Im using OpenGL for an app that im trying to make. I've been learning from the apress book Beggining iPhone Games Development. The problem I have is that a texturedQuad which is a subclass of my mesh class doesn't seem to be rendering properly. (Although it works in the simulator.) The quad renders as just a plain colors that I have set in the texturedQuad class and doesn't seem to be rendering the texture. This is in a class that is called MenuOptionObject.m which is the actual object that I

问题 I have a view, that contains a submit button, and on submit I need to render a partial view in the same page. I noticed that when I use render partial in controller, the other view opens in another page. So based on this answer Rendering a partial from a controller in rails I did the following: in my controller I added this to the main action (manage_payments): def manage_payments @guardian = Guardian.find(params[:id]) @students=Student.find_all_by_sibling_id(@guardian.ward_id) if request

问题 My previous problem was fixed after I rewrote my block.cs class, however, I have one final problem: I have a list of 256 blocks each with 12 triangles and 36 vertices. When I am rendering these blocks using: blocks.ForEach(block => block.Draw(spriteBatch, camera, effect)); They do render, but the game speed drops intensely, to about 0.25 FPS. Each block has a different texture. Should 3072 triangles and 9216 vertices cause this much of a problem? My render code: public void Render

问题 I'm using this table component with radioboxes (Row selection(Single)) and I want to update the react state to the currently selected row. A function called onRowSelect shows the row selected. To update the state to the row selected, I created a function called showRow() , which is called in onRowSelect. However, I keep getting a this.showRow() is not a function error. I'm using showRow() outside the render function because I need to update the state with the currently chosen row. class

问题 I am trying to toggle class in one of my react component. The idea is to add class when the mouse enter and to remove the class when the mouse leave only in the element only the element in where the user perform the actions. However this is not the case as when the action is being performed all the element with the function are behaving equally. This is my code so far: export default class Projects extends Component{ constructor(){ super(); this.state = { isHovered : false } } //handle mouse

问题 I'm using this method to simulate the outline of a point. GLfloat points[graph->vertexCount * 6]; GLfloat outlinePoints[graph->vertexCount * 6]; for (int i = 0 ; i < graph->vertexCount; i++) { outlinePoints[i*6] = (graph->vertices[i].x / (backingWidth/2) ) - 1; outlinePoints[i*6+1] = -(graph->vertices[i].y / (backingHeight/2) ) + 1; outlinePoints[i*6+2] = 0.9; outlinePoints[i*6+3] = 0.9; outlinePoints[i*6+4] = 0.9; outlinePoints[i*6+5] = 1.0; points[i*6] = (graph->vertices[i].x /
