I have this code <hgroup id="subheader"> <h1>lorem ipsum</h1> <h2>ipsum lorem</h2> <a href="#" class="arrow-down">read More</a> </hgroup> I want the link to have a border with a down triangle at the bottom. But it has to be transparent, because it goes in front of an image. Is that possible? 回答1: The shape given in question is a bit complex to achieve with full transparency because of the area cut by the arrow having to be transparent too. Because of this, the techniques that are generally used for creating such

Generally i know how to solve this problem mathematic but i don't know how to do that in python ( no use string and write no more than 2 lines)

I have spent a good 2 hours trying to work with addArcWithCenter... , lineCapStyle and lineJoinStyle etc but nothing seems to work for me. UIBezierPath *bezierPath = [UIBezierPath bezierPath]; CGPoint center = CGPointMake(rect.size.width / 2, 0); CGPoint bottomLeft = CGPointMake(10, rect.size.height

I have looked all day and still can't understand how to calculate the normals for this. Does each vertex have its own normals or does each triangle have its own normals? Can someone point me in the right direction on how to edit my code to incorporate normals? struct vertices { GLfloat x; GLfloat y; GLfloat z; }vertices[10000]; GLuint indices[60000]; /* 99..9999 98..9998 ........ 01..9901 00..9900 */ void CreateEnvironment

The triangle should grow but now change angles and be rotated by a point while being centred at the middle of the triangle. This is my problem, it is currently dragging by the point 3 and rotating around point 1. I have an array of values x and y and it stores 4 values each containing the initial point first at ordinal value 0 and point 1 2 and 3 at the corresponding values. ` public class DrawTriangle extends

I tried this to be a solution: .triangle:after { position:absolute; content:""; width: 0; height: 0; margin-top:1px; margin-left:2px; border-left: 10px solid transparent; border-right: 10px solid transparent; border-bottom: 10px solid white; } .triangle:before { position:absolute; content:""; width: 0; height: 0; border-left: 12px solid transparent; border-right: 12px solid transparent; border-bottom: 12px solid black; } You can see it working at Triangle . This is working, but with a trick of

My code for printing the bottom level stars is the following: void tri_func(num) { int row; int c=1; int j; for ( row = 1 ; row 回答1: Well, if you have n lines, the first line should contain n-1 spaces and a * . The i th

Is there a way I can create a 3d rigid body (in bullet) from a mesh (in three.js)? Here is an example: http://kidzinski.com/miamisura/lazy3d/ (please wait a second for the 3d model to download). I have a cloth falling on a 3d body and I need to simulate collision of this cloth with the body. I am new to these frameworks sorry if I fundamentally misunderstood something. 回答1: It looks like you can do some work

First is the shader, then the implementation of the glwiedget class which is derived from QOpenglWidget . // shaders here static const char * vertexShaderSource = "#version 330 core\n" "in vec3 posAttr;\n" //"attribute lowp vec3 colAttr;\n" //"varying lowp vec4 col;\n" //"uniform highp mat4 matrix;\n" "void main() {\n" //" col = colAttr;\n" " gl_Position = vec4(posAttr, 1) ;\n" "}\n" ; // fragment shader static const char * fragmentShaderSource = "#version 330 core\n
