Hi there, I am new in OpenGL. I try to plot chart, data i get fron file segy. How can I convert data from std::vector to coordinates OpenGL?
example of code:
void RenderingWindow::render(const RenderState *state)
{
auto const f = QOpenGLContext::currentContext()->functions();
if (!f) {
return;
}
m_vec = {-0.515932, -0.591868, -0.678215, -0.776175, -0.000887242, -1.01284}; //convert to coords
f->glClearColor(0.2, 0.2, 0.2, 1.0);
f->glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
GLuint vbo;
f->glGenBuffers(1, &vbo);
f->glBindBuffer(GL_ARRAY_BUFFER, vbo);
f->glBufferData(GL_ARRAY_BUFFER, m_vec.size() * sizeof(float), m_vec.data(), GL_STATIC_DRAW);
f->glVertexAttribPointer(0, 2, GL_FLOAT, GL_FALSE, 2 * sizeof(float), (void*)0);
f->glEnableVertexAttribArray(1);
f->glLineWidth(1);
f->glDrawArrays(GL_LINE_STRIP, 0, m_vec.size());
f->glDisableVertexAttribArray(0);
f->glBindBuffer(GL_ARRAY_BUFFER, 0);
f->glDeleteBuffers(1, &vbo);
}
