java - Draw a line in Open GL ES 2.0 -


i'd draw line of fixed color given 2 points can change @ will.

i have other objects i've got shaders , textures on take code snippets on have way more code think necessary simple line. i'm new open gl es 2.0 , cant figure out how put yellow 3d line on screen without making holder object.

this in ondrawframe method of renderer

    private void drawtestline() {        float[] lineendpoints = new float[6];        system.arraycopy(nearpoint, 0, lineendpoints , 0, nearpoint.length);        system.arraycopy(farpoint, 0, lineendpoints , 3, farpoint.length);  //need here        gles20.gldrawarrays(gles20.gl_lines, 0, 2);     }

vertex shader:

attribute vec3 a_posl; uniform mat4 u_mvpmatrix; void main() {     gl_position = u_mvpmatrix*vec4(a_posl,1.0); }

fragment shader:

precision mediump float; uniform vec4 u_linecolor; void main() {     gl_fragcolor = u_linecolor; }

once have these shaders, pass position, color , matrix using glvertexattribpointer , gluniforms

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
