c++ - Isolating a string of 1's in a character -

i need come function takes char , index of set bit in , isolates string of 1's containing bit. i.e. char isolate(unsigned char arg, int i); for example: isolate(221,2) return 28 (11011101 >>> 00011100) isolate(221,6) return 192 (11011101 >>> 1100000) a lookup table seems clumsy solution require ~256*8=2048 entries. i thinking of examining each individual bit left , right of index: char isolate(char arg, int i) { char result=0; char mask = 1<<i; for(char mask = 1<<i; arg & mask != 0; mask>>=1) result |= mask; for(char mask = 1<<i; arg & mask != 0; mask<<=1) result |= mask; return result; } but seems bit ugly. how can better this? warning: none of tested or relevant*, may interesting. isolating rightmost run of 1s easy, this: x ^ (x & ((x|(x-1))+1)) (explanation below), let's work that. first x|(x-1) smears rightmost 1 right, adding 1 turns bits 0 includin...

Generating Vertices in OpenGL ES 2.0 Vertex Shader -

i trying draw triangle 3 vertices a,b,c. typically, have these 3 vertex co-ordinates in array , pass attribute vertex shader. but , possible generate these vertex co-ordinates within vertex shader rather passing attribute (i.e. per vertex co-ordinate value corresponding vertex position). if yes, sample program support ? thanks. you can create variables in vertex shader , pass fragment shader. example: vertex shader precision highp float; uniform float u_time; uniform float u_texturesize; uniform mat4 u_mvpmatrix; attribute vec4 a_position; // passed fragment shader. varying vec2 v_texturecoordinate0; void main() { // create texture coordinate v_texturecoordinate0 = a_position.xy / u_texturesize; gl_position = u_mvpmatrix * a_position; } and fragment shader : precision mediump float; uniform float u_time; uniform float u_pixel_amount; unifor...
